Which of the following particles
have an electric charge of positive one? Photon, electron, antimuon, tauon,
proton, neutron, antitauon, muon.
We can begin by eliminating
particles we are most familiar with, the electron and the neutron. We only want particles that have an
electric charge of positive one. And we know that the electron has a
charge of negative one. Therefore, this cannot be one of
our particles. We also know that a neutron is
neutral or has a charge of zero. Therefore, we can eliminate neutron
from our list as well. Along with the electron and the
neutron, we should also be very familiar with the proton. A proton has an electric charge of
positive one and is therefore one of the particles we are looking for. Looking back at our list, the first
particle, the photon, the particle nature of light, does not have any charge and
therefore can be eliminated from our list.
This leaves us with particles that
are considered the charged leptons, antimuon, tauon, antitauon, and muon. We can recall the six charged
leptons. The electron, which we have already
eliminated, the muon, and the tauon all have a charge of negative one. And their associated antileptons,
the positron, the antimuon, and the antitauon, all have charges of positive one. Referring back to our list, all of
the particles that fall under the negative one column, the tauon and the muon, can
now be eliminated. The antimuon and the antitauon are
charged leptons with a value of positive one charge. The particles from the list that
have an electric charge of positive one are the antimuon, proton, antitauon.
