Since an up quark (u) has a charge of 2e/3, where –e is the charge of the electron, and a down quark (d) has a charge of –e/3, neutrons are neutral and protons have a positive charge.There are two types of hadrons: baryons and mesons. Every baryon is made up of three quarks and every meson is made of a quark and an antiquark. For example, the proton is composed of two up quarks and a down quark (uud). All quarks have the same quantum numbers for such properties as spin, size, parity, etc. The six quarks, namely the up quark (u), the down quark (d), the strange quark (s), the charm quark (c), the top quark (t), sometimes also called truth quark, and the bottom quark (b), also dubbed beauty quark, carry a colour charge. The bosons that act on colour, are called gluons, which are the carriers of the colour interaction. Step 3: Up quarks in a proton: Protons are made up of uud quarks = 2 up quarks. Step 4: Up quarks in a neutron: Neutrons are made up of udd quarks = 1 up quark. Step 5: Total number of up quarks: 26 protons x 2 up quarks = 52 up quarks. 30 neutrons x 1 up quark = 30 up quarks. 52 + 30 = 82 up quarks.7 Mei 2017 ...
