Question

•what is proton?
•what is electron?
•who discovered neutron?​

Answer 1

Explanation:

Rutherford determined that such a zero-charge particle would be difficult to detect by available techniques. By 1921 Rutherford and William Harkins had independently named the uncharged particle the neutron, while about that same time the word proton was adopted for the hydrogen nucleus

Answer 2

Explanation:

A stable subatomic particle occurring in all atomic nuclei, with a positive electric charge equal in magnitude to that of an electron is called proton.

A stable subatomic particle with a charge of negative electricity, found in all atoms and acting as the primary carrier of electricity in solids is called electron.

Rutherford determined that such a zero-charge particle would be difficult to detect by available techniques. By 1921 Rutherford and William Harkins had independently named the uncharged particle the neutron, while about that same time the word proton was adopted for the hydrogen nucleus.
