Electronegativity may be described as the power of an atom to attract electrons to itself in a chemical bond. It is the most important chemical parameter in calculating the type of
A single covalent bond is build when two atoms share a pair of electrons. Triple and double bonds can be formed when two or three such pairs are shared. A Lewis structure is a repr
