Question

If atomic number of inert gas is $Z$, then ionic bond is formed between:

• A. $(Z-1)$ and $(Z+1)$
• B. $(Z-2)$ and $(Z+2)$
• C. both (a) and (b)
• D. none of these

Answer 1

The correct option is C both (a) and (b)

If Z is the atomic number of the inert gas, then
$\begin{array}{ccc}(z-1)& \Rightarrow & halogens(z+1)=alkalimetals\\ (z-2)& \Rightarrow & oxygenfamily;(z+2)=alkalineearthmetals\end{array}\}Fromioniccompound$
