1.	d. The approximate radius of a ll-atom is0.0 nm, and that of proton is 1.3 10 Wm. Assuming loth en is l ,5% 10-4 m. Assuming both diehydrogen atom and the proton to be spherical, calculato fraction of the spsce in an stom ofhydrogen thalis occupied by the nueleus
Answer» 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 thanks to help me

Answer»

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
