Who among the following has coined the term ‘Quark’, the fundamental particles that make up protons and neutrons in an atomic nucleus? Correct Answer Murray Gell-Mann

The correct answer is option 2 i.e Murray Gell-Mann.

• Electrons are considered fundamental particles, but protons and neutrons are not: they consist of quarks and gluons.
• Quark is a type of elementary particle and a fundamental constituent of matter.
• It combines to form composite particles called hadrons, the most stable of which are protons and neutrons.
• Gell-Mann and George Zweig independently proposed the existence of a new type of particle that made up particles such as neutrons and protons. Hence option 2 is correct.
• Quark is of six types as - up, down, strange, charm, bottom and top.
• Up, charm and top quarks have a charge of +2/3 while down, strange and bottom have a charge of -1/3.
