Question

The melting point of metal potassium is 63.5 oC while the melting point of Ti is 1660 oC. why?

Answer 1

Explanation:

Titanium has a stronger metallic bonding compared to potassium

The atomic size of Titanium much lower than that of potassium, so the bonding between Titanium atoms is stronger than that of potassium. Hence, the melting point of Titanium is much higher than that of potassium.

Answer 2

Answer:

because in Titanium there is close packing of electrons in comparison to potassium in the outermost valance cell, due to strong positive charge in the nucleus of the atom.
