Vedclass · Accepted Answer

$Li^{+}$

Vedclass · Answer

(A) The ionisation potential refers to the energy required to remove an electron from a gaseous atom or ion. Comparing the species: $Li^{+}$ $(1s^2)$ has a stable noble gas configuration (isoelectronic with $He$). $Mg^{+}$ $([Ne] 3s^1)$ has one electron in the $3s$ orbital. $Al^{+}$ $([Ne] 3s^2)$ has two electrons in the $3s$ orbital. $Ne$ $(1s^2 2s^2 2p^6)$ is a neutral noble gas. Among these,$Li^{+}$ has the highest effective nuclear charge relative to its size and a very stable $1s^2$ configuration,making it the most difficult to remove an electron from. Therefore,$Li^{+}$ has the highest ionisation potential.
