The Diameter of an atom is about

The Diameter of an atom is about:

1. 10^-5 m
2. 10^-10 m
3. 10^-15 m
4. 10^-20 m

Correct answer: 2. 10^-10 m

The diameter of an atom is of the order 10^-10 m. Usually the diameter of an atom is about 0.1 to 0.5 nanometers (i.e 1 × 10⁻¹⁰ m to 5 × 10⁻¹⁰ m)

For Example:

• Diameter of hydrogen atom is 1.06× 10⁻¹⁰ m
