Final answer:
An atom with a radius of 1.0 × 10⁻¹⁰ m is 100,000 times bigger than its nucleus, which has a radius of 1.0 × 10⁻¹⁵ m.
Step-by-step explanation:
To calculate how much bigger an atom is than its nucleus, we compare their radii. The radius of the nucleus is given as 1.0 × 10⁻¹⁵ m, while the radius of the atom is 1.0 × 10⁻¹⁰ m.
To find out how much larger the atom is, we divide the radius of the atom by the radius of the nucleus.
The calculation is as follows: Atom radius ÷ Nucleus radius
= (1.0 × 10⁻¹⁰ m) ÷ (1.0 × 10⁻¹⁵ m)
= 10⁵
Therefore, an atom is 100,000 times bigger than its nucleus in terms of radius.
