Which substance has ionic bonds LiI H2O NH3 Br2 Which substa

Solution

There are two different ways to determine whether the bond is ionic or not. They are

1. If a compound is made of a metal atom and a non-metal atom, then the bonding will be ionic

2. And it can also be decided from the electronegativity difference between the two atoms of a molecule. If the electronegativity difference is over or close to 1.7 (this value varies in literature from 1.6-2.1), then the bond between the atom might be ionic.
