Which of the following subatomic particle/s of an atom has/have no charge (neutral)?
a) proton
b) neutron
c) electron
d) all of these
Which of the following subatomic particle/s of an atom has/have negative charge?
a) proton

Where the electrons are present in an atom?
a) inside the nucleus
b) in between the orbits
c) in orbits around the nucleus
d) none of these
