Question

Where is the location in an atom of the lightest subatomic particle?

Answer 1

Answer:

The lightest subatomic particle is electrons which revolve around the nucleus in the orbits.

Answer 2

The lightest subatomic particle, the electron, revolves around the nucleus in atomic orbitals or shells.

• There are three subatomic particles in an atom, which include electrons, neutrons, and protons.
• Electrons are negatively charged whereas protons are positively charged.
• Neutrons are neutral in nature and have no charge.
• Mass of a proton is 1.6726×10⁻²⁷ kg and a neutron has a similar mass, 1.6749×10⁻²⁷ kg.
• Mass of an electron is 9.109×10⁻³¹kg. Hence, it is the lightest of all the three subatomic particles.
• Protons and neutrons are present in the nucleus of the atom and are termed nucleons.
• Electrons revolve in fixed shells around the nucleus.
