Summary Introduction
Introduction:
A covalent bond is formed by sharing of electrons between two atoms. Atoms with partially full outermost electron shells can stable themselves by sharing electrons with each other, filling both of their outer shells. Covalent bonds may produce polar or nonpolar molecules. Covalent bonds may be formed between atoms of same element or atoms of different elements.
