Detailed explanation-1: -Electrovalent bonds are produced when electrons are transferred from atoms of one element to atoms of another element, producing positive and negative ions. The bond which is formed by the transfer of electrons between the atoms is called electrovalent bond or ionic bond.

Detailed explanation-2: -An ionic bond is formed by the complete transfer of some electrons from one atom to another. The atom losing one or more electrons becomes a cation-a positively charged ion. The atom gaining one or more electron becomes an anion-a negatively charged ion.

Detailed explanation-3: -An ionic bond results from the transfer of an electron from a metal atom to a non-metal atom.

Detailed explanation-4: -The correct answer is (a) ionic. An ionic bond occurs when one or more electrons is passed from one atom to another. This generally stabilizes both atoms by making their outer valence shells full of electrons.

Detailed explanation-5: -Ionic bonds result from the electrostatic attraction between oppositely charged ions, which form when valence electrons are transferred from one atom to another.
