The reason is that electrons are shared in a covalent bond in an ionic bond, it's more like one atom donates an electron to the other atom a lewis structure is named for gilbert n lewis, who introduced the idea in the article the atom and the molecule in 1916. Summary important points to remember electrovalent bonding is essentially the electrostatic force of attraction between the oppositely charged ions covalent bonding is the mutual sharing of electrons leading to non electrostatic binding.
