The fundamental particles:
Although other atomic particles are known, the three fundamental ones are:
Protons. The proton has unit mass and carries a unit positive charge.
Neutron. The neutron has unit mass but no electrical charge.
Electron. The electron has only 1/1836 unit of mass but it carries a unit negative charge.
Thus, although we have 92 types of naturally occurring atoms, they are all built-up from different numbers of these three fundamental particles. Thus our picture of the structure of matter is as shown below.

Can you please give me feedback on my physics assignment.
Charging: During charging the device is linked across a source of D.C. supply having a voltage of about 3 volts. When the circuit is switched on the current flows inside the cell
