Question

The approximate radius of a hydrogen atom is0.05 nm and that of proton is 1.5*10-15 m assume both the hydrogen atom and the proton to be spherical calculate fraction of the space in an atom of hydrogen that is occupied by the nucleus

Answer 1

Area of a sphere :

A = 4πr²

Area of hydrogen atom :

Convert the nm to m

1nm = 1 × 10⁻⁹ M

3.142 × 4 × [0.05 × 10⁻⁹] ² = 3.142 × 10⁻²⁰ M²

Area of hydrogen proton:

3.142 × 4 × [1.5 × 10⁻¹⁵] ² = 2.8278 × 10⁻²⁹ M²

(2.8278 × 10⁻²⁹) ÷ (3.142 × 10⁻²⁰) = 9 × 10⁻¹⁰
