Question

Out of neutron and proton which is slightly heavier ?

Answer 1

Neutron :

1. The neutron is present at the center of the atom.
2. It does not have any charge over it.
3. It is slightly heavier than the proton but 1839 times heavier than the electron.
4. It is represented by “n”.
5. Its mass is $1.6750\times {10}^{-27}\mathrm{kg}$.

Proton:

1. Proton is also situated at the center of the atom.
2. It is a positively charged particle.
3. It is heavier than the electron but lighter than the neutron.
4. It is represented by “p”.
5. Its mass is $1.6727\times {10}^{-27}\mathrm{kg}$

$$\begin{gathered} \mathrm{Order}\mathrm{of}\mathrm{mass}:- \\ \mathrm{Neutron}>\mathrm{Proton}>\mathrm{Electron} \end{gathered}$$

Hence, the neutron is slightly heavier than the proton.
