Question

define a.proton b.nuetron and c. eletron​

Answer 1

Answer:

A proton is a subatomic particle, symbol p or p⁺ , with a positive electric charge of +1e elementary charge and a mass slightly less than that of a neutron. Protons and neutrons, each with masses of approximately one atomic mass unit, are collectively referred to as "nucleons

A neutron is a sub-atomic particle with no net electrostatic charge, with a very similar mass to a proton. Neutrons are thought to comprise of one up quark of charge +2/3 and two down quarks of charge -1/3 each, resulting in a net charge of zero. Neutrons are present in almost all atomic nuclei except for Hydrogen.
