Question

In which of these statements are protons, electrons, and neutrons correctly compared?

Quarks are present in protons and neutrons but not in electrons.
Quarks are present in protons, neutrons, and electrons.
Quarks are present in neutrons and electrons but not in protons.
Quarks are present in protons and electrons but not in neutrons.

Answer 1

Quarks are present in protons and neutrons but not in electrons. Quarks are sub-atomic particles that have mass, but not an integer of charge. Protons and neutrons are made up of quarks, but electrons are not since they are energy travelling with a charge of energy, not matter with mass. Quarks have mass, therefore cannot be in electrons.

Answer 2

Considering the definition of quarks, the correct statement is the first option: Quarks are present in protons and neutrons but not in electrons.

What are quarks

Quarks are certainly some of the smallest particles in the universe. They are elemental, indivisible and cannot be divided into smaller pieces.

Quarks are the only fundamental particles that freely interact with all four elementary physical forces: gravitational force, electromagnetic force, strong nuclear force, and weak nuclear force.

There are six different types of quarks and isolated quarks are not found in nature, they are always found in groups, called hadrons, of two or three quarks, which are known as mesons and baryons respectively.

In summary, quarks are massive elementary particles that come together by the strong nuclear force to form the matter of the atomic nucleus and hadrons. That is, various species of quarks combine in a specific way to form particles such as protons and neutrons.

Correct statement

Then, taking into account the definition of quark, the correct statement is the first option: Quarks are present in protons and neutrons but not in electrons.
