less than the actual charge of $+3$

(C) In $Lithium$ $(Z=3)$,the $1s^2$ electrons shield the $2s$ electron from the full nuclear charge.Due to this shielding effect,the $2s$ electron experiences an effective nuclear charge $(Z_{eff})$ which is less than the actual nuclear charge of $ 3$.The formula is $Z_{eff} = Z - \sigma$,where $\sigma$ is the shielding constant.
