Question
Explain concept with example/explain with the help of a balanced equation.
Ionic bond and ionic compounds
Solution
- The compounds formed from two units, namely cation and anion are called ionic compounds.
- 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.
- 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.
- 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.
