Question

Name the three sub particle of an atom, their charges and their mass.

Answer 1

The three sub particles of an atom are protons, electrons and neutrons.

Explanation:

Neutrons, electrons, and protons are the three sub atomic particles of an atom. Electrons are negatively charged, protons are the positively charged and neutrons are neutral. Electrons are having 9.1×$10^{-31}$ kg, protons and neutrons are having a mass of 1.67×$10^{-24}$ kg.

As protons possess positive charges, so the atomic number of protons will be 1 , similarly, the atomic number of electrons will be -1 and neutron is zero. So, electrons, protons and neutrons combine together to form the atom.

As the electrons present with negative charge and protons with positive charge, along with this the protons number are equal to electrons number, this confirm the neutral nature of atoms.
