Question

Compared to the nonmetals in Period 2, the metals in Period 2 generally have larger

(1) ionization energies
(2) electronegativities
(3) atomic radii
(4) atomic numbers

Answer 1

The answer is atomic radii; the size or radii of an atom increases from left to right, versus the ionization energies and electronegativities of atoms which increase from right to left.
