23. 12. Nucleon is composed of A. Protons and Neutrons B. Protons and Electrons C. Electrons and Neutrons D. Only Neutrons ​

Answer:

Nucleon is composed of Protons and Neutrons

Explanation:

The atomic nucleus consists of nucleons—protons and neutrons. Protons and neutrons are made of quarks and held together by the strong force generated by gluon exchange between quarks

Answer:

A. protons and Neutrons

Explanation:

A Neutron is composed of one up quark and two down quarks. They are an integral part of the nucleus but they cannot exist as independent nucleons because the atomic nucleus holds them together with a strong force.
