Vedclass · Answer

(A) Assertion $(A)$: $Be$ and $Mg$ have very high ionization enthalpies due to their small atomic size. Reason $(R)$: Because of their high ionization enthalpies,the electrons in $Be$ and $Mg$ are too strongly bound to be excited to higher energy levels by the energy available in the Bunsen flame. Consequently,they do not impart any characteristic colour to the flame. Therefore,both $(A)$ and $(R)$ are true,and $(R)$ is the correct explanation of $(A)$.

Assertion $(A)$: $Be$ and $Mg$ do not impart any colour to the flame.
Reason $(R)$: The electrons in them are too strongly bound to get excited by the energy of the flame.
