Question

What are the three fundamental particles of the atom?

Answer 1

Atom:

• An atom is the smallest unit of matter.
• It contains charged and uncharged particles.

An atom has three sub-atomic particles that are discussed below:

1. Protons:

• Proton is a positively charged particle.
• Each proton carries positive charge $\left(+1\right)$.
• The number of protons of an atom is equal to the atomic number of an element.

2. Electrons:

• An electron is a negatively charged particle.
• Each electron carries negative charge $\left(-1\right)$.

3. Neutrons:

• Neutrons are uncharged particles, they do not carry any charge on them.
• They are present inside the nucleus along with protons.
