Question

The ions S^2-, Cl-, K+ and Ca^2+ all have the configuration (1s)^2(2s,2p)^8(3s,3p)^6 and Slater Z^* values (for a 3p electron) of 4.75, 5.75, 7.75 and 8.75 respectively (in that order). Their radii therefore follow:

Accepted Answer

S^2- > Cl- > K+ > Ca^2+

Answer

Ca^2+ > K+ > Cl- > S^2-

Answer

Cl- > S^2- > K+ > Ca^2+

Answer

S^2- > K+ > Cl- > Ca^2+

The ions $S X^{2 -}$ , $Cl X^{-}$ , $K X^{+}$ and $Ca X^{2 +}$ all have the configuration $(1 s)^{2} (2 s, 2 p)^{8} (3 s, 3 p)^{6}$ and Slater $Z^{*}$ values (for a $3 p$ electron) of 4.75, 5.75, 7.75 and 8.75 respectively (in that order). Their radii therefore follow:

Answer: B
