Question
Explain concept with example/explain with the help of a balanced equation.
Ionic bond and ionic compounds
✓

Answer

  1. The compounds formed from two units, namely cation and anion are called ionic compounds.
  2. The cation and anion being oppositely charged, there is an electrostatic force of attraction between them. This force of attraction between cation and anion is called as the ionic bond.
  3. The number of cations and anions in a compound and the magnitude of the electric charge on them is such that the positive and negative charges balance each other. As a result, an ionic compound is electrically neutral.
  4. For example, ionic compound sodium chloride $(NaCl)$ is formed as sodium metal gives away one electron while the nonmetal chlorine takes up one electron. $Na^+$ and $Cl^−$ ions formed are held together by attractive force called ionic bond.
