Question

protons and neutrons are made up of what subatomic particles?
protons and neutrons are basic particles, and cant be subdivided more than they already are
quarks
nuclei
electrons

Explanation:

To determine the subatomic particles that make up protons and neutrons, we analyze each option:

• The first option is incorrect because protons and neutrons are not fundamental (basic) particles and can be subdivided.
• Quarks are known to be the subatomic particles that compose protons and neutrons. A proton is made of two up - quarks and one down - quark, and a neutron is made of one up - quark and two down - quarks.
• Nuclei are made up of protons and neutrons, not the other way around, so this option is incorrect.
• Electrons are subatomic particles that orbit the nucleus and are not part of the composition of protons or neutrons.

Answer:

The correct option is the one with "Quarks" (the second option in the list of choices).
