Question

How is sodium oxide formed by the transfer of electrons? explain why ionic compounds have high melting and boiling point?

Answer 1

Ionic compound have higher melting point because as it is formed by transfer of electrons , it have a higher force of attraction due to which a large amount of energy is required for melting it. The first answer is given in the pic :-

Answer 2

Sodium oxide formation:

• The sodium oxide forms the ionic compound.
• This compound has the high melting and boiling point.
• It has high opposite charge that is positive and negative which attract each other. Hence this compound has high melting and boiling point because they are strongly bonded.
• In this ionic process, each sodium atom gives the one electron to oxygen atom, allowing the oxygen to have full shell with eight electrons.

Reason on ionic compounds have high melting and boiling point:

• Ionic compound has "high melting" and "high boiling points" due to the "strong electrostatic force" of attraction among the oppositive charged ions.
• Since, there is requirement of huge amount of energy for breaking the  "strong bonding force" between those ions.
