Web30 dec. 2024 · MgCl2 is an Ionic compound, not a covalent. Since the gap in electronegativity value between magnesium (1.31) and chlorine (3.16) is large, therefore, the bond formed in Magnesium chloride is Ionic. It consists, of two ions, Mg 2+ and 2Cl –, both of these are held together by ionic bonding. WebThe metallic bond can be described as the attractive force present between negatively charged mobile electrons and positively charged metallic ions. This force of attraction is used to hold the metal atoms together in the metallic crystal. Metallic bond examples are: Sodium Aluminium Magnesium Copper Iron
