Question

Chemistry

consider the isoelectronic ions Cl- and K+. Which ion issmaller?

ssuming the core electrons contribute 1.00 and valence electronscontribute nothing to the screening constant, S, calculate Zeff forthese two ions.

Repeat this calculation using slater's rules to estimate thescreening constant, S. For esoelectronic ions how are effectivenuclear charge and ionic radius related?
