The unequal sharing of electrons forms a polar covalent bond. Introduction: An element is a pure substance of one type of atom or it is a species of an atom having the same number of protons in its atomic nucleus. For example, there are 118 known elements in the periodic table. A compound is the combination of two or more different elements. A covalent bond is formed when same or different elements share electrons. For example, water ( H 2 O ), in which two hydrogen atoms are joined with one oxygen atom or sharing of electrons takes place. A molecule is the combination of two or more of the same type of elements. For example, H 2 is the combination of two hydrogen atoms. Octet rule: It is a rule which is followed when compound formation occurs. According to this rule, atoms of main-group elements tend to combine in such a way that each atom has eight electrons in its valence shell, giving it the same electron configuration as a noble gas. The electronic configuration is the arrangement of electrons according to the increasing energies of the orbitals Electronegativity is the tendency of an atom to attract a shared pair of electrons.
