Question

select the correct answer. which subatomic particle has negligible mass and travels around outside the nucleus? a. proton b. neutron c. electron d. orbital

Explanation:

Electrons are subatomic particles. They have a very small (negligible) mass compared to protons and neutrons. Protons and neutrons are located in the nucleus of an atom, while electrons travel around outside the nucleus in electron - shells (or orbitals, but orbital is not a subatomic particle). Protons have a positive charge and a significant mass, neutrons have no charge but also a significant mass. So the subatomic particle that has negligible mass and travels around outside the nucleus is the electron.

Answer:

C. electron
