Answer
Lewis model can also be used to define the ionic bonding.According the octet rule,atoms with their 8 electrons in their outer shell are stable.
For example Sodium(Na) has one valance electron.Chlorine(Cl) has 7 valance electrons.So,Na can donate one electron to Cl to form an ionic bond and both atoms can attain octet state. So Na and Cl atom can form NaCl,a ionic compound.
Work Step by Step
Lewis dot method is based on the octet rule in which we have to find the probability of combining of two atoms through their valance electron.
