Which particles are located in the nucleus of an atom?Multiple choice question.protons onlyneutrons onlyneutrons and protonsprotons and electrons

Step 1: Break Down the Problem

The question asks about the particles that are found in the nucleus of an atom. The options provided include:

1. Protons only
2. Neutrons only
3. Neutrons and protons
4. Protons and electrons

Step 2: Relevant Concepts

To answer this question, it is important to recall the structure of an atom:

• The nucleus of an atom is composed of protons and neutrons.
• Electrons are located outside the nucleus.

Step 3: Analysis and Detail

1. Protons: Positively charged particles located in the nucleus.
2. Neutrons: Neutral particles that also reside in the nucleus.
3. Electrons: Negatively charged particles that orbit the nucleus.

Step 4: Verify and Summarize

Given the definitions above, protons and neutrons are the particles found in the nucleus of an atom. Electrons are not part of the nucleus but are present in electron shells around it.

Final Answer

The correct answer is neutrons and protons.
