WebIonic bonds form when the charges between the metal cation and non-metal anion are equal and opposite. This means that two Cl−1 anions will balance with one Ca+2 cation. This makes the formula for calcium chloride CaCl2. For the example Aluminum Oxide Al2O3. Aluminum has an oxidation state of +3 or Al+3. http://www.endmemo.com/chem/common/gold.php WebThese are the strongest bonds between atoms which can be further divided as follows: (i) Ionic (or electrostatic) bond. (ii) Covalent (or atomic or homopolar) bond. (iii) Metallic bond. 2. Secondary (or Molecular) Bonds: Attraction forces (also called ven der Waals forces) exist between atoms or molecules. These bonds are weaker than primary bonds. dailymotion love is in the air capitulo 144
