The \( 1^{\text {st }}, 2^{\text {nd }} \) and the \( 3^{\text {rd }} \) ionization enthalpies \( \mathrm{I}_{1}, \mathrm{I}_{2} \) and \( \mathrm{I}_{3} \),
\( \mathrm{P} \) of four atoms with atomic numbers \( \mathrm{n}, \mathrm{n}+1, \mathrm{n}+2 \) and

WV \( \mathrm{n}+3 \), where \( \mathrm{n}10 \), are tabulated below. What is the value of \( n \) ?
