In a calcium atom in the ground state, the electrons that possess the least amount of energy are located in the
hram777 [196]

Answer is: (1) first electron shell.

Aufbau principle is a scheme used to reproduce the electron configurations of the ground states of atoms by successively filling subshells (orbitals) with electrons in a specific order.  

Filling subshells in the following order: 1s, 2s, 2p, 3s, 3p, 4s, 3d, 4p, 5s, 4d, 5p, 6s, 4f, 5d, 6p, 7s, 5f.  

For example, atom of calcium.  

Atomic number of calcium is 20, it means that it has 20 protons and 20 electrons, so atom of calcium is neutral.  

Electron configuration of calcium atom: ₂₀Ca 1s² 2s² 2p⁶ 3s² 3p⁶ 4s².

Estimate the crystal field stabilization energy for the octahedral ion hexacyanomanganate(III) , if the wavelength of maximum ab
SOVA2 [1]

Answer:

The crystal field stabilization energy for the octahedral ion hexacyanomanganate(III) , if the wavelength of maximum absorption for the ion is 600 nm is -<u> 1987.59kJ/mole</u>

Explanation:

Lets calculate -:

 Crystal field stabilization energy -

                    E=\frac{hc}{\pi }

   where h = planks constant = 6.626\times10^-^3^4 Js

             c= velocity of light = 3\times10^8m/second

           \pi =wavelength=600nm=600\times10^-^9m

           E=\frac{6.626\times10^-^3^4\times3\times10^8}{600\times10^-^9}

                =0.033\times10^-^1^6 J/ion

              = 0.033\times10^-^1^6\times6.023\times10^2^3

             = 0.198759\times10^7 J/mole  = 1987.59\times10^3J/mole

             = 1987.59kJ/mole

 Thus , the crystal field stabilization energy for the octahedral ion hexacyanomanganate(III) is  1987.59kJ/mole
