Protons and neutrons are present in the dense, central core of an atom, called its ______

Options

A. Nucleus
B. Eelctron
C. Orbits
D. Nuclear pore

Answer

**Step-by-Step Solution:**

1. **Understanding the Structure of an Atom**: Atoms are made up of three primary subatomic particles: protons, neutrons, and electrons. Protons and neutrons are located in the central part of the atom, while electrons orbit around this central core.

2. **Identifying the Central Core**: The central part of an atom where protons and neutrons are located is known as the nucleus. This is a dense region that contains most of the atom's mass.

3. **Charge of Subatomic Particles**: Protons carry a positive charge, while neutrons have no charge (they are neutral). Therefore, the overall charge of the nucleus is positive due to the presence of protons.

4. **Final Answer**: The dense, central core of an atom, where protons and neutrons are present, is called its **nucleus**.
