Question

The nuclear particle carrying a charge of +1e is the

Answer 1

electron neutron or proton

Answer 2

proton has a charge of +1e
an electron has a charge of -1e (electron is often written as an e with a minus 1 on the super script to denote it's negative charge) In the fact +e and -e you are using, it is taken from electron
and a neutron as the name implies(neutron from neutral) is neutral (no charge on it)
