Electron

Electric charge -1

It's found outside the nucleus

It's mass is negligible

Proton

It's mass is 1

The electric charge is +1

it's found in the nucleus

Neutron

It's mass is 1

The electric charge is 0

It's found in the nucleus

Explanation:

Every atom consists of three sub-atomic particles which are protons, neutrons and electrons.

Inside the nucleus of an atom, there will be only protons and neutrons. Whereas electrons revolve around the nucleus of an atom.

Protons have a positive charge, neutrons have no charge and electrons have a negative charge.

Mass of these subatomic particles are as follows.

Proton :

Neutron :

Electron :

Hence, we can conclude that the properties of sub-atomic particles are matched as follows.

- Its electrical charge is -1.

- It's found outside the nucleus.

- Its mass is negligible.

- Its electrical charge is +1.

- Its found inside the nucleus.

- It's mass is 1.

- Its electrical charge is 0.

- It's found inside the nucleus.

- It's mass is 1.

a 20-cm-long, cylindrical graphite (pure carbon) rod is inserted into an oxidizing atmosphere at 1145 k and 1.013 x 105 pa pressure. the oxidizing process is limited by the diffu- sion of oxygen counterflow to the carbon monoxide that is formed on the cylindrical surface.
