Question

Write any three conditions for the formation of the ionic bonds

Answer 1

they have high m.p and b.p.
they should be solid
soluble in water

Answer 2

ANSWER-》》

1-)Electronegativity Difference -- greater the electronegative difference between the two combining atoms stronger is the bond formed.

2-)Lower Ionisation Potential -- lesser is the energy required to remove electron easilya cation is formed.

3-)High Electron Affinity -- more is the tendency to accept electron easily an anion is formed.
