Also calculate the wavelength of a free electron with a kinetic energy of 2 eV. Answer: The wavelength of a 2 eV photon is given by: l = h c / E ph = 6.625 x 10-34 x 3 x 10 8 /(1.6 x 10-19 x 2) = 621 nm. where the photon energy was multiplied with the electronic charge to convert the energy in Joule rather than electron Volt. Jul 23, 2020 · Periods are indicated by a number, 1, 2, 3, etc. which represent the energy level, or shell of electrons. The first period, or row, has only one energy level that can hold a total of two electrons. Period 2, with a second shell, can hold a total of eight (8) electrons, also known as the octet rule.

So the electron configuration for Fe is [Ar] 3d^6 4s^2. Fe^2+ means that 2 electrons are taken away. You start removing e- from the outermost shell. The outermost shell, in this case, is the 4s orbital. So removing 2 electrons would leave you with the electron configuration of [Ar] 3d^6. Hope this helps!

Methods.The s sublevel has just one orbital, so can contain 2 electrons max. The p sublevel has 3 orbitals, so can contain 6 electrons max. The d sublevel has 5 orbitals, so can contain 10 electrons max. And the 4 sublevel has 7 orbitals, so can contain 14 electrons max. Electron Configurations - Solutions Note: The electron configurations in this worksheet assume that lanthanum (La) is the first element in the 4f block and that actinium (Ac) is the first element in the 5f block. If your periodic table doesn’t agree with this, your answers for elements near the f-orbitals may be slightly different. However, as you go down the Group, there are more and more examples where the oxidation state is +2, such as SnCl 2, PbO, and Pb 2+.. With tin, the +4 state is still more stable than the +2, but by the time you get to lead, the +2 state is the more stable - and dominates the chemistry of lead.

SOLUTION Iodine (group 7A) has 7 valence electrons; each chlorine (group 7A) also has 7; an extra electron is added to account for the 1- charge of the ion. Therefore, the total number of valence electrons is 7 + 4(7) + 1 = 36. The I atom is the central atom in the ion. Electron cloud definition is - the system of electrons surrounding the nucleus of an atom.

The electron configuration describes the distribution of electrons in the shell of an atom at various energy states. This is described by the occupied sub-shells. The shell number is followed by the letter of the sub-shell, with the number of electrons in the shell indicated by a superscript number.

They all have four electrons in their outer shell. The orbital structure for germanium is 2-8-18-4. You can understand why there are similarities to silicon and tin when you see their orbital structures are 2-8-4 and 2-8-18-18-4 respectively. Watch for the 4. Even though electron repulsion effects by other electrons with n = 3 will tend to aid the ionization process, they will make similar contributions for S and Cl. Thus, the order based on a consideration of Zeff is the appropriate one. When an electron is added, in each case, it will go into a 3p orbital which already contains a single electron. The secondary quantum number, l, divides the shells up into smaller groups of subshells called orbitals. The value of n determines the possible values The fourth and final quantum number is used to indicate the orientation of the two electrons in each orbital. The values for ms are +1/2 and -1/2.Oct 22, 2007 · Lets say we take Helium, which has 2 electrons. These 2 electrons will be just enough to fill Shell 1. If I give them some more energy, one of those electrons jumps up to Shell 2. So there’s 1 electron in Shell 1 and 1 in Shell 2. But as soon as it can, this electron will fall back to Shell 1 again. When it does, it will release energy as light. Each electron in an atom is described by four different quantum numbers. The first three (n, l, ml) specify the particular orbital of interest, and the All orbitals that have the same value of n are said to be in the same shell (level). For a hydrogen atom with n=1, the electron is in its ground state; if the...arises a dipole magnetic field. In the case of the electron, the dipole moment is found to be given by µS = − e 2me gS (6.10) where me and −e are the mass and charge of the electron, S is the spin angular momentum of the electron, and g is the so-called gyromagnetic ratio, which classically is exactly equal to one, Once formed, the Sn-Cl bonds in the [SnCl6]2― ion are all alike.

So, 1 refers to the first shell, 2 the second shell, and so on. For any electron shell n, that shell can hold a total of 2n² electrons. Accordingly, shell 1 can hold a total of 2 electrons, shell 2 can hold a total of 8 electrons, shell three a total of 18, etc.
