Quarks are entities that have
no charge, combination of these are present in protons and electrons
Fractional charges, combination of these are present in protons and neutrons
integer charges, combination of these are present in protons, electrons and neutrons
fractional charges, combination of these are present in protons and electrons
Quarks are fundamental matter particles that are constituents of neutrons and protons. They have fractional electric charges.
Why are protons positively charged, electrons negatively charged and neutrons have neither negative or positive charge?
