What properties do protons and electrons share

Charge  and spin

Explanation:

Your instructor is probably expecting you to say "charge ".

In one sense that is correct. Both particles have a charge, but that on a proton is 1+ while on an electron it is 1-.

There is one property they have in common that is identical: they both have spin ½.

a boiling water reactor does not boil the water. a pressurized water reactor boils the water faster. a pressurized water reactor is heated directly by the core. a pressurized water reactor does not use fission.
