The melting point for potassium (K) is 63.5 °C whereas melting point of barium (Ba) is 727 °C.

<h3>Reason for high melting point</h3>

The melting point of barium is higher than potassium because of the presence of metallic bonding in the giant structure of a barium metal is very strong. These metallic bonds requires large amounts of energy for breaking.

While on the other hand, potassium has large atomic size than barium so the melting of potassium is lower than barium so we can conclude that melting point of potassium is lower than barium atom.
