Question

a sub-atomic particle with negligible mass . please answer this fast​

Answer 1

Answer:

electron

Explanation:

Electron is the sub-atomic particle with negligible mass .The rest mass of the electron is 9.1093837015 × 10−31 kg, which is only 1/1,836the mass of a proton. An electron is therefore considered nearly massless in comparison with a proton or a neutron, and the electron mass is not included in calculating the mass number of an atom.

Answer 2

Answer:

The heavy, dense central core of an atom that houses the protons and neutrons. ... A chargeless subatomic particle that has approximately the same mass as a proton and that is housed within the nucleus. Electron. A negatively charged subatomic particle that has negligible mass and moves around in a cloud around the nucleus
