Chemistry Question on Classification of elements & periodicity in properties

Which of the following sets has strongest tendency to form anions?

A

Ga,In,Tl\text{G}\text{a},\text{I}\text{n},\text{T}\text{l}

B

Na,Mg,Al\text{N}\text{a},\text{M}\text{g},\text{A}\text{l}

C

N,O,F\text{N},\text{O},\text{F}

D

V,Cr,Mn\text{V},\text{C}\text{r},\text{M}\text{n}

Answer

N,O,F\text{N},\text{O},\text{F}

Explanation

Solution

N, O and F (p - block elements) are highly electronegative non metals and will have the strongest tendency to form anions by gaining electrons from metal atoms.
