Compare the properties of electrons, protons, and neutrons.

Electron	Proton	Neutron
1. Negative charge	Positive charge	No charge
2. Mass is negligible (1/1800 is time of protons)	Mass is 1 a.m.u	Mass is 1 a.m.u
3. Get attracted toward +ve charge	Get attracted towards -ve charge	Do not get attracted as they are neutral
4. Present outside the nucleus	Present in the nucleus	Present in the nucleus of an atom.

 [Extra information: Atoms consist of three basic particles: protons, electrons, and neutrons.

1. Electron is a negatively charged subatomic particle. It can be either free or bound to the nucleus of an atom. Electrons in atoms exist in spherical shells of various radii, revolving around the positive nucleus. The charge on a single electron is considered as the unit electrical charge. It is represented by symbol e⁻ or β⁻.

2. Proton- Positively charged subatomic particle forming part of the nucleus of an atom and determining the atomic number of an element. It weighs 1 amu.

3. Neutron- A subatomic particle forming part of the nucleus of an atom. It has no charge. It is equal in mass to a proton or it weighs 1 amu.]
