It is an alkali metal phosphate, Read More Is Na3PO4 an Acid or Base?Continue, Nitrogen is neither a cation or an anion. The electron donor becomes a cation (positively charged ion) and the electron acceptor becomes an anion (negatively charged ion). The higher the electron gain enthalpy, the easier it is to form an anion. This difference results in an electron(s) being transferred from the metal (lower electronegativity) to the non-metal (higher electronegativity). Covalent bond does not involve the formation of ions. What nerves can be damaged in lithotomy position? Examples of ionic compounds are Sodium chloride, Ammonium, Hypochlorite, Lithium fluoride, Potassium phosphate and so on. These shared electrons are known as shared pairs. Element Valency The loss and gain of electrons by the atoms lead to the formation of ions. Ionic bonding is observed because metals have few electrons in their outer-most orbitals. When we have a non-metal and a non-metal the compound is considered non-polar covalent.Because we have a non-metal and non-metal in Br2 there will be no difference in electronegativity between the non-metal and non-metal.
