Answer:
The representative particle for these elements is the molecule. Likewise, all molecular compounds such as H 2 O and CO 2 exist as molecules and so the molecule is their representative particle. For ionic compounds such as NaCl and Ca(NO 3 ) 2 , the representative particle is the formula unit.

The answers to the given questions are provided below:
1. The representative particle of ionic compounds is the formula unit (option d).
- The attraction forces of negatively charged and positively charged species combine to generate ionic compounds. NaCl, for example, contains the ions Na+ and Cl⁻.
- It denotes the ratio of ionic particles present in an ionic compound, which is computed using the formula, hence the name formula unit.
2. The particles contained in one mole of any kind of substance are 6.02 × 10²³ particles (option b).
- This number denotes the number of particles present in a mole of any substance, whether they are ionic particles, atomic particles, or molecules.
- This quantity is known as the avogadro constant or Avogadro number and is calculated theoretically.
