Question

question 1-7
what subatomic particles are located in the nucleus of an atom?
○ protons (positive charge) and neutrons (neutral charge)
○ electrons (negative charge) and protons (positive charge)
○ neutrons (neutral charge) and electrons (negative charge)
○ protons (positive charge), neutrons (neutral charge), electrons (negative charge)

Explanation:

To determine the subatomic particles in the nucleus, we recall atomic structure: protons (positive charge) and neutrons (neutral charge) are in the nucleus, while electrons orbit outside. So the correct option is the first one.

Answer:

A. protons (positive charge) and neutrons (neutral charge)
