A covalent bond is possible between Similar and Dissimilar atoms.
A covalent bond is possible between Similar and Dissimilar atoms.
Two atoms with same electronegativity or similar electronegativity can form a covalent bond.
For example, $2 H$ atoms combine to form a covalent bond in hydrogen molecule.
Also, one $C$ atom combines with $4 H$ atoms to form four $C - H$ covalent bonds in methane.
