Explain the inner-shell electrons than lighter alkali metals

Reference no: EM13561923

Select the false statement below.

A. Generally speaking, as you go down a group in the periodic table, there is successively greater shielding of the outer-shell electrons by the inner-shell electrons.

B. Generally speaking, the heavier alkali metals can be predicted to exhibit greater shielding of the outer-shell electrons by the inner-shell electrons than lighter alkali metals.

C. Generally speaking, as you go across a period in the periodic table, the effective nuclear charge (Zeff) decreases because each successive element contains more protons in the nucleus than the previous element and the outer electrons are all in the same shell as you go across a period.

D. Generally speaking, non-metallic elements have greater effective nuclear charge (Zeff) than metallic elements in the same period.
