Sn ground state electron configuration

Mentioned in the Hebrew scriptures, tin is of ancient origins. Tin is an element in Group 14 the carbon family and has mainly metallic properties.

Tin has atomic number 50 and an atomic mass of Early metal smiths were quick to learn that mixing copper with tin created a more durable metal bronze and it is principally for its alloys that tin is valued today. Named after the Etruscan god Tinia, the chemical symbol for tin is taken from the Latin stannum. The metal is silvery white and very soft when pure.

It has the look of freshly cut aluminum, but the feel of lead. Polished tin is slightly bluish. It has been used for many years in the coating of steel cans for food because it is more resistant to corrosion than iron. It forms a number of useful low-melting alloys solders which are used to connect electrical circuits.

Bending a bar of tin produces a characteristic squealing sound called "tin cry". Tin shares chemical similarities with germanium and lead. Tin mining began in Australia in and today Tin is used extensively in industry and commerce. There are 10 known stable isotopes of Tin, the most of any elements on the periodic table. Tin has 3 allotropes: alpha, beta and gamma tin. Alpha tin is the most unstable form of tin. Beta tin is the most commonly found allotrope of tin and gamma tin only exists at very high temperatures.

Tin, although it is found in Group 14 of the periodic table, is consistent with the trend found in Group 13 where the lower oxidation state is favored farther down a group. Tin has a ground state electron configuration of 1s 2 2s 2 2p 6 3s 2 3p 6 4s 2 3d 10 4p 6 5s 2 4d 10 5p 2 and can form covalent tin II compounds with its two unpaired p-electrons. In the three dimensional figure below, the first and most inner electron shell is represented by blue electrons, the second electron shell made up of eight electrons is represented by red electrons, the third shell containing eighteen electrons is represented with green electrons, and the next outer electron again contains eighteen electrons and represented in purple.

Nearly half of the tin metal produced is used in solders, which are low melting point alloys used to join wires. Solders are important in electrician work and plumbing.

Tin is also used as a coating for lead, zinc, and steel to prevent corrosion. Tin cans are widely used for storing foods; the first tin can was used in London in Write an equation for the reaction of tin with water. Under what conditions does this reaction take place? Introduction Mentioned in the Hebrew scriptures, tin is of ancient origins. Table 1 : Basic Properties of tin color white with blueish tinge hardness softer than gold, harder than lead atomic radius pm density 5.

How do you write the electron configuration of tin?

Reactions of Tin Hydrogen Tin not affected Nitrogen Tin absorbs it instead of hydrogen in electric discharge Argon No sign of a combination of Tin with Argon Fluorine Does not react with Tin at low temperatures, but at degrees Celsius they form stannic fluoride. Isotopes There are 10 known stable isotopes of Tin, the most of any elements on the periodic table.Hello everyone.

I was checking my homework answers and came up with a dilema. All the textbooks and yahoo answers state that the 5s orbita fills up before the 4d orbital aka lower in energy. This is how I remembered it from chemistry in high school, and the logic of lower energy levels make sense. Take out the electrons with higher energy level, but with one exception: Electrons in an outer s orbital must be taken out before the electrons in the d orbital.

There are no outer-level s electrons in any ion. They are always lost first. They are outer level, after all. Thank you. Update: Hello everyone. Answer Save. Think of it this way when dealing with cations: 1. Fill up the ground state electron configuration of the element at task 2. Take out the electrons with higher energy level, but with one exception: Electrons in an outer s orbital must be taken out before the electrons in the d orbital Following these steps you will have no problem dealing with any cations isotopes.

An atom's electron configuration is a numeric representation of its electron orbitals. Electron orbitals are differently-shaped regions around an atom's nucleus where electrons are mathematically likely to be located. An electron configuration can quickly and simply tell a reader how many electron orbitals an atom has as well as the number of electrons populating each of its orbitals.

Once you understand the basic principles behind electron configuration, you will be able to write your own configurations and tackle those chemistry tests with confidence. Write the electron configuration to display the number of electrons in the atom, divided into orbital sets. The orbital sets go in a predetermined order and have a set number of electrons per set, so fill in the orbitals according to the number of electrons in your atom.

Find your atom's atomic number. Each atom has a specific number of electrons associated with it. Locate your atom's chemical symbol on the periodic table.

The atomic number is a positive integer beginning at 1 for hydrogen and increasing by 1 for each subsequent atom. The atom's atomic number is the number of protons of the atom — thus, it is also the number of electrons in an atom with 0 charge. Determine the charge of the atom.If we can't tunnel through the Earth, how do we know what's at its center?

At room temperature it is a solid and has a melting point of The electron configuration of tin II cation is [Kr]5s2. Tin does not officially have an orbital notation because it is an exception to the Rule of Demetres. Instead, it only has an electron configuration of 1s2 2s2p6 3s2p6d10 4s2p6d10 5s2p2.In atomic physics and quantum chemistrythe electron configuration is the distribution of electrons of an atom or molecule or other physical structure in atomic or molecular orbitals.

Electronic configurations describe each electron as moving independently in an orbital, in an average field created by all other orbitals. Mathematically, configurations are described by Slater determinants or configuration state functions. According to the laws of quantum mechanicsfor systems with only one electron, a level of energy is associated with each electron configuration and in certain conditions, electrons are able to move from one configuration to another by the emission or absorption of a quantum of energy, in the form of a photon.

Knowledge of the electron configuration of different atoms is useful in understanding the structure of the periodic table of elements. This is also useful for describing the chemical bonds that hold atoms together. In bulk materials, this same idea helps explain the peculiar properties of lasers and semiconductors. Electron configuration was first conceived under the Bohr model of the atom, and it is still common to speak of shells and subshells despite the advances in understanding of the quantum-mechanical nature of electrons.

An electron shell is the set of allowed states that share the same principal quantum numbern the number before the letter in the orbital labelthat electrons may occupy. An atom's n th electron shell can accommodate 2 n 2 electrons, e. The numbers of electrons that can occupy each shell and each subshell arise from the equations of quantum mechanics, [2] in particular the Pauli exclusion principlewhich states that no two electrons in the same atom can have the same values of the four quantum numbers.

Physicists and chemists use a standard notation to indicate the electron configurations of atoms and molecules. For atoms, the notation consists of a sequence of atomic subshell labels e. For example, hydrogen has one electron in the s-orbital of the first shell, so its configuration is written 1s 1.

For atoms with many electrons, this notation can become lengthy and so an abbreviated notation is used. The electron configuration can be visualized as the core electronsequivalent to the noble gas of the preceding periodand the valence electrons : each element in a period differs only by the last few subshells.

Phosphorus, for instance, is in the third period. This convention is useful as it is the electrons in the outermost shell that most determine the chemistry of the element. For a given configuration, the order of writing the orbitals is not completely fixed since only the orbital occupancies have physical significance.

The first notation follows the order based on the Madelung rule for the configurations of neutral atoms; 4s is filled before 3d in the sequence Ar, K, Ca, Sc, Ti. It is quite common to see the letters of the orbital labels s, p, d, f written in an italic or slanting typeface, although the International Union of Pure and Applied Chemistry IUPAC recommends a normal typeface as used here.

The choice of letters originates from a now-obsolete system of categorizing spectral lines as "sharp", "principal", "diffuse" and "fundamental" or "fine"based on their observed fine structure : their modern usage indicates orbitals with an azimuthal quantum numberlof 0, 1, 2 or 3 respectively. After "f", the sequence continues alphabetically "g", "h", "i" The electron configurations of molecules are written in a similar way, except that molecular orbital labels are used instead of atomic orbital labels see below.

The energy associated to an electron is that of its orbital. The energy of a configuration is often approximated as the sum of the energy of each electron, neglecting the electron-electron interactions. The configuration that corresponds to the lowest electronic energy is called the ground state. Any other configuration is an excited state.

Atoms can move from one configuration to another by absorbing or emitting energy. Usually, the excitation of valence electrons such as 3s for sodium involves energies corresponding to photons of visible or ultraviolet light.

The excitation of core electrons is possible, but requires much higher energies, generally corresponding to x-ray photons. The remainder of this article deals only with the ground-state configuration, often referred to as "the" configuration of an atom or molecule.
