Answer the following questions.

Name the fundamental particles in an atom.

The fundamental particles in an atom are protons, neutrons and electrons.

i. Protons(p) = Proton is the positively charge fundamental particle and is resides in the nucleus. The positive charge of proton(p⁺) is of the same magnitude as that of electron’s negative charge(e^-).

ii. Neutron(n) = Neutron has no charge and is also resides in the nucleus. The mass of a neutron is almost equal to that of proton.

iii. Electron(e^-) = Electron is a negatively charge fundamental particle and it moves around the nucleus in particular orbits.
