The radius of atom is of the order of 1 Å and radius of nucleus is of the order of fermi. How many magnitudes higher is the volume of atom as compared to the volume of nucleus ?

Explanation

To solve the problem of comparing the volume of an atom to the volume of its nucleus, we will follow these steps:

### Step 1: Identify the given values
- The radius of the atom \( r_a \) is given as \( 1 \) Å (angstrom).
- The radius of the nucleus \( r_n \) is given as \( 1 \) fermi.

### Step 2: Convert the given values to meters
- \( 1 \) Å = \( 10^{-10} \) meters
