The various of three quarks

Answer 1

quarks make up protons and neutrons and come in three colours. Red green and blue. each flavour has 6 'flavours' up, down, top, bottom, strange, charmed. refer to the standard model of particle physics for more info

---------------------------------------

Three quarks are u quark, d quark and s quark.
The charge of these quarks will be:
u quark has positive charge and equals to 2/3 of charge of a proton.
d quark and s quark have negative charge which equals to 1/3 of the elementary charge on a proton.
s quark differs from d quark because of its strangeness quantum number.
For d quark no strangenes quantum number where as s quark has strangeness number equal to --1.
So u and d quarks are responsible to form neutron and proton.
Hence for a neutron to become neutral, it is assumed to be made up of one u and two d quarks. (udd)
For proton as it has one e as the charge, it is assumed to be made up of two u and one d quarks. (uud)
Thus the quarks are the building blocks of elementary particles such as proton and neutron.
