Answer 1

Explanation:

(1 to 3). Also the effective nuclear charge exerting attractive force on the valence electrons

less than the actual nuclear charge. Thus, the number of valen

is small. As a combined effect of these two factors metals have a

valence electrons to form cations having a stable noble gas configuration. This tendency of
