Question

Which of the following species has the highest ionization potential ? (A) Ne (B) Al+ (C) Mg+ (D) Li+

Tardigrade Admin · Accepted Answer

Both Ne and Li+ have noble gas configurations. Out of these two Li+ will have more ionisation potential due to smaller size and more nuclear charge per electron.

Q. Which of the following species has the highest ionization potential ?

Ne

$A l^{+}$

$M g^{+}$

$L i^{+}$

Both Ne and $L i^{+}$ have noble gas configurations. Out of these two $L i^{+}$ will have more ionisation potential due to smaller size and more nuclear charge per electron.
