Final answer:
The nucleus of an atom contains both protons and neutrons, which are two of the three basic particles of atoms. The number of protons determines the atomic number and therefore, the identity of an element
Step-by-step explanation:
The statement is correct. The nucleus of an atom indeed contains both protons and neutrons. These are two of the three basic particles of atoms, with the third being electrons, which orbit the nucleus. The number of protons determines the atomic number and thus, the identity of an element. The combined number of protons and neutrons make up the atomic mass.
