Question

If $Q$ reacts with flourine and oxygen, the molecular formula of fluoride and oxide will be respectively:

• A. $Q{F}_3$, $Q_2{O}_3$
• B. $QF$, $Q_{2}O$
• C. $Q{F}_2$, $QO$
• D. none of these

Answer 1

Answer: (B)

$QF$, $Q_{2}O$

Q forms stable unipositive ion as it has minimum $I{E}_1$.
So, it will form QF and $Q_{2}O$.
