In an atom, where is a neutron located?

• A. In the nucleus
• B. In the outermost energy level
• C. Orbiting the nucleus
• D. In the electron cloud

Answer: (A)

Verified step by step guidance

1. Recall the basic structure of an atom, which consists of a nucleus and an electron cloud surrounding it.
2. Understand that the nucleus contains protons and neutrons, which are collectively called nucleons.
3. Recognize that electrons are located in the electron cloud, which is outside the nucleus and arranged in energy levels or orbitals.
4. Identify that neutrons, unlike electrons, do not orbit the nucleus but are found inside the nucleus along with protons.
5. Therefore, conclude that a neutron is located in the nucleus of an atom.
