Question

The size of an atom is determined by which sub-atomic particle of the atom?

Answer 1

1. Yes, the size of the atom is dependent on the sub-atomic particles such as electrons and protons.

2. With the increase in the number of electrons, the size of the atom increases.

3. This is because, with the increase in number of electrons, the shell occupancy increases as only two electrons can be accommodated in each shell. So, as number of shells increase, the radius increases.
