Covalent bond between identical atoms
Covalent bond between identical atoms
The two electrons forming the bond are shared equally and symmetrically between the two atoms.
Covalent bond between dissimilar atoms
Covalent bond between dissimilar atoms
The electrons are attracted more towards the atom with higher electronegativity, leading to an uneven distribution of electron density.
