Center of the atom that contains protons and neutrons

Center of the atom that contains protons and neutrons

• A. Atom
• B. Protons
• C. Neutrons
• D. Nucleus

Answer: (D)

The center of the atom is called the nucleus, where protons and neutrons are located. The nucleus is a very dense, small core at the heart of the atom. Protons carry a positive charge and neutrons have no charge, and together they form most of the atom’s mass. Electrons orbit the nucleus in surrounding regions, held in by the attraction to the positively charged protons. So, when the prompt asks for the center that contains protons and neutrons, the nucleus is the correct concept. The whole atom includes electrons as well, and the individual particles—protons or neutrons—are components inside the nucleus, not the center itself.
