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. |
