Hadrons are made of but they have an electric charge. This means that they never
have a charge that is 2/3 or -1/3 or other such fraction.
They can be divided into two classes:
are made of quarks.
A proton is made of quarks and quarks.
NOTE The only stable baryon
into which other baryons will eventually decay is the .
Remember GCSE - what can a
neutron decay into during the emission of Beta radiation?
A and an . (This also produces an

One example of a meson is a pion (+),
which is made of an
quark and a
The antiparticle of a meson just has its quark and antiquark
switched, so an antipion (-)
is made up from a
quark and an
The kaon (K-)
meson lives much longer than most mesons, which is why it was called
