Baryon
charge
From the classifications of nuclear particles,
baryon fall under a class or family of
particles called hadrons. These hadrons
are composite particles with quarks as their fundamental particle.
Protons and
neutrons are the two types of baryons
they both fundamentally made up of three
quarks.
The baryon charge are charges on this quarks
contained in this proton and neutron, a proton has to up quark and one down quark,
the two up quark has each an electrical
charge of positive +2/3 while the down quark has a charge of negative -1/3, the
sum of these charge will give us the charge on the proton.
Adding the
total sum of these charges +2/3 +2/3-1/3
we a positive 1, therefore , the
baryon charge rge on proton is +1.
The neutron also has three quarks, two down
quark and one up quark, the two down quarks has a charge of a charge of -1/3
while the up quark has the charge of positive +2/3, summing the total charges
on the individual quarks making up the neutron we will have a charge of zero,
therefore the baryon charge on neutron is zero.
The antiparticle of baryon are called
antibaryons likewise their charges are
also opposite that of their respective particles because they have constituent antiquarks
instead of quarks. E.g neutron has two anti-up quark and one anti-down quark
and therefore they have opposite charge or antibaryon charge respectively.
