Question

Which set have the strongest tendency to form anions?

• A. $Ga,In,Te$
• B. $Na,Mg,Al$
• C. $N,O,F$
• D. $V,Cr,Mn$

Answer 1

The correct option is C $N,O,F$

$Ga,In,Te$ are much below in the periodic table and hence, exist in positive oxidation states.

$Na,Mg$ and $Al$ are metals and exist in positive oxidation states.

$N,O$ and $F$ are non-metals and have a tendency to gain electrons and form anions.

$V,Cr$ and $Mg$ are metals and are electropositive, thereby forming cations.
