Answer»

Greek philosopher Demokrits name the undivided particle of substance as atom.

An atom is made up of three particles:

1. Proton (p)

2. Electron (e)

3. Neutron (n)

An atom has two structural parts

1. Nucleus (inner part)

2. Electric shell (outer part)

The inner part of atom is called Nucleus. It has two particles:

1. Proton (p) – It is positively changed.

2. Neutron (n) – It is electrically neutral.

The outer part of atom consist of negatively charged particles called electron (e). They, circulate around nucleus in definite orbits.
