Question

The mass of the neutron is less than that of an electron.

• A. True
• B. False

Answer 1

The correct option is B False

• Electrons, protons, and neutrons are the subatomic particles of an atom.
• Protons and neutrons are present inside the atom while electrons are present outside the nucleus.
• Electrons are negatively charged while protons are positively charged. Neutrons do not carry any charge.
• Protons and neutrons are heavier than that electrons.
• Mass of the electron is $9.1\mathrm{x}{10}^{-31}\mathrm{kg}$.
• Mass of the neutron is $1.6749\mathrm{x}{10}^{-27}\mathrm{kg}$, nearly 1839 times greater than that of the electron.

Thus, the given statement is false, i.e., The mass of the neutron is greater than that of an electron.
