Which of the following statements correctly describes a proton?

• A. A proton is found in the nucleus.
• B. A proton has a mass about the same as a neutron.
• C. A proton is attracted to electrons because of their charges.
• D. A proton has a 1+ charge.

Answer: (D)

Verified step by step guidance

1. Step 1: Understand the basic properties of a proton. A proton is a subatomic particle found in the nucleus of an atom. It is one of the primary components of atomic nuclei, along with neutrons.
2. Step 2: Consider the mass of a proton. A proton has a mass that is approximately equal to that of a neutron. Both protons and neutrons have a mass of about 1 atomic mass unit (amu), making them similar in mass.
3. Step 3: Examine the charge of a proton. A proton carries a positive charge, specifically a +1 charge. This is a fundamental characteristic of protons, distinguishing them from neutrons, which have no charge.
4. Step 4: Explore the interaction between protons and electrons. Protons are attracted to electrons due to their opposite charges. Electrons have a negative charge, and the electrostatic force between opposite charges leads to attraction.
5. Step 5: Review the location of protons within an atom. Protons are located in the nucleus, which is the central part of an atom. This is a key aspect of atomic structure, as the nucleus contains both protons and neutrons.
