$\underline\red{Answer}$

The electronegativity increases across te period

Reason-

The atomic radius decreases and the nuclear charge increases

The electronegativity decreases down the group

Reason-

The atomic size increases and the nuclear charge decreases

Answer 2

Ans.The electronegativity increases across te period

Reason-

The atomic radius decreases and the nuclear charge increases

The electronegativity decreases down the group

Reason-

The atomic size increases and the nuclear charge decreases
