Question

use and throw into to write the electronic configuration of CE 3 + ion and calculate its magnetic moment I'm on the basis of spin only formula​

Answer 1

Answer:

Explanation:

Use Hund's rule to derive the electronic configuration of Ce3+ ion, and calculate its magnetic moment on the basis of 'spin only' formula. ... (Ti2+ to Mn2+ electronic, configuration changes from 3d2 to 3d5 but in 2nd half i.e. Fe2+ to Zn2+ it changes from d6 to d10).

Answer 2

Answer:

Electronic configuration of Ce:

Ce:

${1s}^{2} {2s}^{2} {2p}^{6} {3p}^{2} {3p}^{6} {3d}^{10} {4s}^{2} {4p}^{6} {4d}^{10} {5s}^{2} {5p}^{6} {4f}^{1} {5d}^{1} {6s}^{2}$

∴ Electronic configuration of Ce +3 using hund's rule is,

${ce}^{3} : {1s}^{2} {2s}^{2} {2p}^{2} {3s}^{2} {3p}^{6} {3p}^{6} {3d}^{10} {4s}^{2} {4p}^{6} {4d}^{10} {5s}^{2} {5p}^{6} {4f}^{1} or ,  {ce}^{3 + :} (xe) {4f}^{1}$

Hope it's help you....
