Question

screening constant of magnesium​

Answer 1

Explanation:

For each electron in an atom, Slater's rules provide a value for the screening constant, denoted by σ. The effective nuclear charge may be defined as the actual nuclear charge (Z) minus the screening effect caused by the electrons intervening between the nucleus and valence electron.

Answer 2

Answer:

9.15

Explanation:

Mg = (1s)2  (2S,2P)8  3S2

(1 x .35) + (8 x .85) + (2) =  9.15
