Question

two elements A and B hevr the electronic configuration 2,8,2 and 2,6 respectively. Name the type of bond formed between these two elements. Why does the compound so formed has a high melting point?

Answer 1

The compound formed will be electrovalent bond as A is an electropositive element and B is electronegative element.So there will be transfer of electrons.

The compound has high melting and boiling points because it has strong electrostatic forces of attraction between its molecules and it requires a large amount of energy to break these electrostatic forces of attraction.

Answer 2

Ionic bond.

As they can easily transfer 2 electrons to form an ionic bond

Since its Ionic bond it has high melting point as Ionic bonds are really strong interactions and ionic solids have really high melting point
