The conditions required for the formation of covalent bond are :
1. The atoms having no tendency to lose electronsform covalent bonds.
2. The two combining atoms should have equal attraction for electrons.
3. Each of the two combing atoms should have 5, 6 or 7 electrons in their valence shells or the outermost shells. In such cases, both the atoms achieve the stable octet by sharing 3,2 or 1 electron pair respectively. The nonmetals of groups VA, VIA and VIIA respectively satisfy this condition and hence they are capable of covalent-bond formation.
4. Covalent bond is favoured most when the combining atoms come from the electronegative elements. Thus, electronegative element + electronegative element—covalent bonding.

Two oppositily charge ions (like possitive charge ion and negative charge ion).Oppositily charge ions attract together.Then electrostatic force holds to keep two atoms each other.The electrostatic force of attraction of each atom is called electrovalent bond.Example NaCl is a electrovalent bond.The conditions for the formation of an electrovalent bond:- (I) Two Oppositily ions (ii) two atoms should have tendency to lose or gain electrons
