Question

5. What are protons and neutrons made up of?

Answer 1

Protons and neutrons are composed of two types: up quarks and down quarks. Each up quark has a charge of +2/3. Each down quark has a charge of -1/3. The sum of the charges of quarks that make up a nuclear particle determines its electrical charge.

Answer 2

Quarks

Step-by-step explanation:

When we break down protons and neutrons, scientists named the building blocks of atoms "quarks". Quarks are considered in the basic basic elementary particles of the universe.
