Comparison of Mass and Charge of Electron, Proton, and Neutron

An atom consists of three primary subatomic particles: protons, neutrons, and electrons. Each of these particles has different properties such as mass and electric charge. Understanding these differences helps us learn more about atomic structure.

1. Electron

Charge: -1 (negative)
Mass: (9.109 × 10^{-31}) Kg

2. Proton

Charge: +1 (positive)
Mass: (1.673 × 10^{-27}) Kg

3. Neutron

Charge: 0 (neutral)
Mass: (1.675 × 10^{-27}) Kg

Comparison Table

Subatomic Particle	Charge	Mass (approx.)	Position in Atom
Electron	Negative (-1)	About 1/1836 of 1 amu	Found outside the nucleus
Proton	Positive (+1)	1 atomic mass unit (amu)	Located inside the nucleus
Neutron	0	1 amu	Located inside the nucleus

Electrons are negatively charged and very light. Protons are positively charged and heavier. Neutrons have no charge and have a mass nearly equal to protons. Together, these particles form the structure of an atom.
