difference between electrons protons and neutrons...also find the relation between the three

Electron

Proton

Neutron

(i)

Electrons are present outside the nucleus of an atom.

(i)

Protons are present in the nucleus of an atom.

(i)

Neutrons are present in the nucleus of an atom.

(ii)

Electrons are negatively charged.

(ii)

Protons are positively charged.

(ii)

Neutrons are neutral.

(iii)

The mass of an electron is considered to negligible.

(iii)

The mass of a proton is approximately 2000 times as the mass of an electron.

(iii)

The mass of neutron is nearly equal to the mass of a proton.

Relation between these three: There is no specific relation between these three. Electrons and neutrons are present in same number in an atom which maintains the stability of the atom.

Even though the neutrons are neutral particles, they serve two important functions in an atom. These are as follows :

  • Neutrons balance mass of the atom.
  • They help in keeping the positively charged protons together in the nucleus. As the protons are positively charged species, they would repel each other (like charges repel each other). The neutrons do not carry any charge and help in binding the protons together in a nucleus by overcoming the repulsive forces between them.

Protons are particles found in the centre (the nucleus) of an atom. Their mass, by convention, is said to be 1. (not 1 gram, ounce or anything - just 1! - It's a number used simply in order to compare it with the other two particles). Its electrical charge is +1 meaning it is positive 

Neutrons are also found in the nucleus along with the protons, and have also a mass of 1 (ie, they are the same as a proton in mass). However, as their name implies, they are electrically neutral having no charge. 

Electrons are found in 'orbits' (actually just areas of space) outside the nucleus. Electrons have a mass of 1/1836 (i.e. nearly 2000 electrons are needed to weigh the same as a proton or neutron). They have an electrical charge of -1 meaning it has a negative charge (ie their charge is identical in strength but opposite to a proton.)
