Answer:
c. protons and neutrons are found in the nucleus
d. protons and neutrons have approximately the same mass
Explanation:
There are three fundamental particles within an atom which are the protons, neutrons and electrons.
The protons are the positively charged particles within an atom
Neutrons do not carry any charges
Electrons are the negatively charged particles.
- Both the protons and neutrons occupy the tiny nucleus at the center of the atom.
- The electrons moves round the nucleus through the orbital space.
- The mass of the protons and neutrons are similar and are assumed to be approximately the same.
