Vedclass · Answer

(B) The first ionisation energy $(I.E.)$ generally increases as we move from left to right across a period in the periodic table due to an increase in effective nuclear charge and a decrease in atomic size.$Li$ $(Z=3)$ and $Be$ $(Z=4)$ belong to the same period ($2^{nd}$ period).Since $Be$ is to the right of $Li$,the first ionisation energy of $Li$ is less than that of $Be$.

The first ionisation energy of lithium $(Li)$ will be
