![]() ![]() As long as the electro-negativity difference is no greater than 1.7, the atoms can only share the bonding electrons. ![]() The electro negativities (electron attracting ability) of the two bonded atoms are either equal or the difference is no greater than 1.7. This kind of bonds occurs mainly between a metallic and a non metallic atom.Ĭovalent bonds are formed as a result of the sharing of one or more pairs of bonding electrons. Ionic bond, also known as electrovalent bond, is a type of bond formed from the electrostatic attraction between oppositely charged ions in a chemical compound. So to stabilize the atom, each atom shares half of its electrons.Ĭovalent bonding is a form of chemical bonding between two non metallic atoms which is characterized by the sharing of pairs of electrons between atoms and other covalent bonds. But apart from Inert gas, this configuration is not present with most of the atoms. Each of these molecular orbits can have a certain number of electrons to form a stable atom. But electrons revolve in orbit around the center. At the centre of the atom, neutrons and protons stay together. The covalent bond is formed when two atoms are able to share electrons whereas the ionic bond is formed when the "sharing" is so unequal that an electron from atom A is completely lost to atom B, resulting in a pair of ions.Įach atom consists of protons, neutrons and electrons. Sodium chloride (NaCl), Sulphuric Acid (H2SO4 ) The two ions are attracted to each other and form an ionic bond. In ionic bonds, electrons are transferred from one atom to another, resulting in two charged ions - one positively charged, and one negatively charged. These two opposite ions attract each other and form the ionic bond. Non-metals(-ve ion) are "stronger" than the metal(+ve ion) and can get electrons very easily from the metal. For stabilization, they share their electrons from outer molecular orbit with others.Īn ionic bond is formed between a metal and a non-metal. Neither atom is "strong" enough to attract electrons from the other. These kinds of bonds occur mainly between a metallic and a non metallic atom.Ī covalent bond is formed between two non-metals that have similar electronegativities. Ionic bond, also known as electrovalent bond is a type of bond formed from the electrostatic attraction between oppositely charged ions in a chemical compound.
