Question

If $Q$ (alkali metal) reacts with fluorine and oxygen, the molecular formula of fluoride and oxide respectively are:

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

Answer 1

The correct option is B $QF,Q_{2}O$

As Alkali metals have stable oxidation state of $+1$, correct molecular formulas would be $QF$ and $Q_{2}O$.
