Which two subatomic particles have the greatest mass?
denpristay [2]

Answer:

PROTON AND NEUTRON

Explanation:

  • The mass of proton is : 1.67*10^{-27}kg

A proton is one of the main particles that make up the atom . The other two particles are neutron and electron. Protons are found in the nucleus of the atom.This is a tiny , dense region at the centre of the atom. Protons have a positive charge of one (+1) and a mass of 1 atomic mass unit ( amu ) , which is about 1.67*10^{-27}kg. Together with neutrons , they make up virtually all of the mass of an atom.

  • The  mass of neutron is also approximately: 1.67*10^{-27}kg but a little more than that .

Atoms of all elements - except Hydrogen , have neutrons in their nucleus . Unlike protons and electrons , these have no charge - they are electrically neutral . The mass of a neutron is slightly greater than the mass of a proton but not very significant
