a.) A typical atom consists of three subatomic particles: protons, neutrons, and electrons (as seen in the helium atom below). Other particles exist as well, such as alpha and beta particles (which are discussed below).

b.) electron :

e−

−1 or 1.602×10−19C. Where −1 represent its one unit negative electrical charge

proton :

p+

+1 or 1.602×10−19C. Where +1 represents one unit +ve electrical charge.

neutron
