of atoms to each other through

, as well as exchanging, of electrons -or electrostatic forces.
The electron pair is attracted to both atomic nuclei, holding them together to form a

bond.
Dative bond is actually a co-ordinate bond; this terminology is mostly used in coordination chemistry. When a species (may be anion or neutral species) donates l.p. of electrons to a species which is either electron deficient or possess energetically susceptible* vacant orbital— results the formation of dative/co-ordination bond.
Covalent bond, in chemistry, the interatomic linkage that results from the

of an electron pair between two atoms. The binding arises from the electrostatic attraction of their nuclei for the same electrons. A covalent bond forms when the bonded atoms have a
