Explanation:

•)Electrons are the negatively charged particles of atom. Together, all of the electrons of an atom create a negative charge that balances the positive charge of the protons in the atomic nucleus.

•)Proton, stable subatomic particle that has a positive charge equal in magnitude to a unit of electron charge and a rest mass of 1.67262 × 10−27 kg, which is 1,836 times the mass of an electron. Proton.

•)Neutron, neutral subatomic particle that is a constituent of every atomic nucleus except ordinary hydrogen. It has no electric charge and a rest mass equal to 1.67493 × 10−27 kg—marginally greater than that of the proton but nearly 1,839 times greater than that of the electron.

♦}Protons are positively charged particles in the nucleus of an atom. Every element in nature or made in a lab has at least one proton. The mass of a proton is the same as a neutron but 1840x greater than the mass of electron. Electrons are negatively charged particles that orbit around the outside of the nucleus.
