Verified step by step guidance1
Identify the three main subatomic particles: protons, neutrons, and electrons.
Recall the charge and location of each subatomic particle: Protons have a positive charge and are located in the nucleus. Neutrons have no charge and are also located in the nucleus. Electrons have a negative charge and are found in the electron cloud surrounding the nucleus.
Evaluate each description given in the problem: Check if the charge and location of the particle match the known properties of protons, neutrons, and electrons.
Analyze the first description: A proton has a positive charge and is found in the nucleus of an atom. This matches the known properties of a proton.
Conclude that the first description is correct based on the properties of subatomic particles.
