Question

State the three subatomic particles in an atom and briefly explain them​

Answer 1

Proton is a nucleon with a positive charge in the center of the atom, neutrons are nucleons which are also in the nucleus, or center of the atom and have no charge. Both protons and neutrons have a mass of 1 atomic mass unit (amu). Electrons are negatively charged and orbit the nucleus and have a mass of 1/1836 amu which is much less then the nucleons

Answer 2

Answer: The three sub-atomic particles are the following: protons, electrons and neutrons.

Explanation: Protons are positively charged particles and are found in the nucleus of an atom. This positively charged particles were associated to Ernest Rutherford with regards to its discovery. Along with the protons in the nucleus there were also neutrons that are neutral in charge. The third subatomic particles were the electrons. They were negatively charged particles and are found in the electron cloud region outside the nucleus. There are specific number of Electrons arrange in each orbitals, since they are prone to be moved in cases of chemical reactions. It was discovered by JJ Thompson using cathode rays and coined its name. For an atom to be electrically neutral or stable the number of electrons and protons must be equal.
