Question

Why Lithium has high melting and boiling point?

Answer 1

Lithium:

1. Lithium is chemically represented by the symbol $\mathrm{Li}$.
2. It has an atomic number of 3.
3. It is a silvery-white alkali metal with a delicate texture.

Property:

1. Because of its very small size, Lithium is known to have a comparatively high ionization enthalpy.
2. Furthermore, this element's crystal lattice binding energy is quite high.
3. These are the reasons for Lithium's high melting and boiling point.

Hence, Lithium has high melting and boiling point because of the high ionization enthalpy and high crystal lattice binding energy.
