Answer
Below labelled diagram shows the representation of an atom as per the modern atomic theory:
The three sub-atomic particles in the atom are:
| S. No. | Sub-atomic particle | Symbol |
|---|---|---|
| 1. | Proton | +1p1 |
| 2. | Neutron | 0n1 |
| 3. | Electron | -1e0 |
Protons and neutrons are found inside the nucleus of the atom. Electrons are distributed across energy levels outside of the nucleus.
