Ionic bond and covalent bond?

In a easy definition ...Ionic bond = the bond that are formed by the reaction of metal with non metals and covalent bond=the bond that form by the reaction of metal with metal

Ionic bond An ionic bond is a type of chemical bond formed through an electrostatic attraction between two oppositely charged ions. Ionic bonds are formed between a cation, which is usually a metal, and an anion, which is usually a nonmetal. Pure ionic bonding cannot exist: all ionic compounds have some degree of covalent bonding. Thus, an ionic bond is considered a bond where the ionic character is greater than the covalent character. The larger the difference in electronegativity between the two atoms involved in the bond, the more ionic (polar) the bond is. Bonds with partially ionic and partially covalent character are called polar covalent bonds. Formation of Sodium Flouride The attraction of oppositely charged atoms and the transfer of electrons leads to the formation of an ionic compound. In this case, NaF. Covalent Bonds A covalent bond involves electrons being shared between atoms. The most stable state for an atom occurs when its valence electron shell is full, so atoms form covalent bonds, sharing their valence electrons, so that they achieve a more stable state by filling their valence electron shell.
