Question

A neutron is formed by an electron and a proton combining together. Therefore, it is neutral.

• A. True
• B. False

Answer 1

The correct option is B False

Neutron:

• James Chadwick in 1932 performed some scattering experiments in which he bombarded some light elements like Beryllium$\left(\mathrm{Be}\right)$ and Boron$\left(\mathrm{B}\right)$ with fast-moving Alpha particles.
• He found that some new particles were emitted that carried no charge i.e were neutral but had mass nearly equal to that of the proton. This particle was termed a ‘Neutron’.
• Thus, a neutron is defined as that fundamental particle that carries no charge but has a mass nearly equal to that of a Hydrogen atom$\left(\mathrm{H}\right)$ or proton.

Therefore, the given statement is false.
