Which of the following statements best describes the relationship between protons and neutrons in an atom?

The relationship between protons and neutrons in an atom is best described by the statement that protons and neutrons are found in the nucleus together. In an atomic structure, protons carry a positive charge and are one of the primary components of the nucleus, alongside neutrons, which are neutral. Together, they form the atomic nucleus, contributing to the mass of the atom and playing a critical role in stabilizing it.

This close association of protons and neutrons within the nucleus is fundamental to the structure of atoms and is essential for understanding atomic behavior, including concepts like atomic mass and nuclear stability. In contrast, protons cannot exist independently of the nucleus in stable isotopes, nor can neutrons alone, as both particles rely on the nuclear forces that hold them together.
