The first one nitrogen is correct.
For the second one, what is the general trend for atomic radii as you move across a period?
As you move across the radii in the period gets bigger?
Since the order is Li, Be, B, C
Since it's asking for "smallest atomic radius? "
Shouldn't it be Li?
so for b) it suppose to be C ?
Thank you, but please tell me if I am correct?
