Which of the following elements has the smallest atomic radius? carbon lithium boron oxygen

Which element has the highest electron affinity?   Na O Ne Mg

Why is agron the smallest than the other elements in period 3?

Identify the wrong statement in the following? Atomic radius of the elements • increases as one moves down the anion, larger is the ionic radius Amongst isoelectronic species, • greater the negative charge on the cation, smaller is the ionic radius Amongst isoelectronic species, • smaller the positive charge on from left to right in the 3nd period of the Atomic radius of the elements • decreases as one moves across the first group of the periodic table None of this

Place the following in order of increasing atomic radius.Sr              H              Ca
