Question

In the transformation: $Na\left(s\right)\to N{a}^{+}\left(g\right)$, the energies involved are

• A. Ionization energy
• B. Sublimation energy
• C. Ionization energy and sublimation energy
• D. Bond dissociation energy

Answer 1

The correct option is C Ionization energy and sublimation energy

$Na\left(s\right)\to Na\left(g\right)$
The energy requires to convert a neutral gaseous atom into an ion is known as ionisation energy. So it first involves the sublimation of solid sodium and then is followed by ionization.
Option c is correct.
