3.2 Distingush between lonic bond
and covalent bond.
Answers
Covalent Bonds Ionic Bonds
Polarity Low High
Formation A covalent bond is formed between two non-metals that have similar electronegativities. Neither atom is "strong" enough to attract electrons from the other. For stabilization, they share their electrons from outer molecular orbit with others. An ionic bond is formed between a metal and a non-metal. Non-metals(-ve ion) are "stronger" than the metal(+ve ion) and can get electrons very easily from the metal. These two opposite ions attract each other and form the ionic bond.

What is it? Covalent 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. 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. These kinds of bonds occur mainly between a metallic and a non metallic atom.
Melting point low High
Examples Methane (CH4), Hydro Chloric acid (HCl) Sodium chloride (NaCl), Sulphuric Acid (H2SO4 )
Occurs between Two non-metals One metal and one non-metal
Boiling point Low High
State at room temperature Liquid or gaseous Solid
Answer:
Differentiate between an ionic bond and a covalent bond.
In ionic bonds, one atom donates an electron to stabilize the other atom. In a covalent bond, the atoms are bound by the sharing of electrons. ... A polar bond is formed by the attraction between oppositely-charged ions.
