Question

how does metallic character and ionization energy of an element depend up on a size of an atom​

Answer 1

$\mathfrak{\huge{\green{\underline{\underline{Answer :}}}}}$

The metallic character increases as you go down a group. Since the ionization energy decreases going down a group (or increases going up a group), the increased ability for metals lower in a group to lose electrons makes them more reactive.

Answer 2

Answer:

Atomic size decreases as we go from left to right, thus its metallic character and ionization energy decreases as its harder for the atom to lose electrons as we move from left to right.
