Salvador Benitez · Answer 1

We simply divide the Mass of Neutron by Mass of electron

= 2 * 10⁻²⁴ / (9 * 10⁻²⁸)

= (2/9) * 10⁻²⁴ ⁻ ⁻²⁸

= (2/9) * 10⁻²⁴ ⁺ ²⁸

≈ 0.2222 ... * 10²⁸ ⁻ ²⁴

≈ 0.2222 * 10⁴

≈ 2222

This is approximately 2000 times.

So:

The mass of a neutron is approximately 2,000 times the mass of an electron

The first option. I hope this explains it.
