C) [A]\[\to \]q, [B]\[\to \]p, [C]\[\to \]s, [D]\[\to \]r
D) [A]\[\to \]r, [B]\[\to \]p, [C]\[\to \]q, [D]\[\to \]s
Correct Answer: A
Solution :
[a][a] Have same number of electrons - So isoelectronic species |
[b] Has metallic as well as non-metallic properties-semi metal |
[c] Exist as mono atomic molecules & are held together by weak vander Waal's forces-so radius is defined as van Waal's radius |
[d] Energy required to remove an electron from valence shell of a gaseous atom is called I.E. |
