COVALENT BOND IONIC BOND 1.A covalent bond is formed between two non-metals An ionic bond is formed between a that have similar electronegativities, neither atom metal and a non-metal. Non metals “strong” enough to attract eletrons from the other. (-ve ion) are “stronger” than the For stabilization, they share electrons from outer metal (+ve ion) and can get electrons molecular orbits with others. very easily from the metals. These 2 form an ionic bond. 2. Have a definite shape no definite shape 3. covalent bonding is a form of chemical bonding Ionic bond, also known as electro- Between tow non-metallic atoms, which is valent bond is a bond formed from Characterized by the sharing of electrons between electrostatic attraction between atoms and other covalent bonds. oppositely charged ions in a chemical compound. These kinds of bonds occur mainly between a metallic and non metallic atom. 4. low melting point high melting point 5.examples: Methane (CH4), Hydro Chloric (NaCl) Sodium chloride Acid (HCL) Sulphoric Acid H2SO4 6. boiling point low boiling point high 7. state at room temperature – liquid or gas State at room temperature - solid
