    Which of the following is the correct location, in an atom, for protons (p), neutrons (n) and electrons (e)?   - ProProfs

    Which of the following is the correct location, in an atom, for protons (p), neutrons (n) and electrons (e)?  

    • I

    • II

    • III

    Correct Answer
    A. III
    Explanation
    The correct location for protons (p), neutrons (n), and electrons (e) in an atom is in the nucleus for protons and neutrons (III). Electrons are found in energy levels or orbitals surrounding the nucleus.

    Which of these has a negative charge?

    • Electrons

    • Protons

    • Neutrons

    Correct Answer
    A. Electrons
    Explanation
    Electrons have a negative charge. Electrons are subatomic particles that orbit around the nucleus of an atom. They carry a negative charge and are responsible for the flow of electricity. Protons, on the other hand, have a positive charge, while neutrons have no charge and are neutral.

    Where are protons located?

    • In the nucleus

    • Outside of the nucleus

    Correct Answer
    A. In the nucleus
    Explanation
    Protons, which are positively charged particles, are located in the nucleus of an atom. The nucleus is the central part of an atom that contains protons and neutrons. Electrons, which are negatively charged particles, are found outside of the nucleus in energy levels or orbitals. Therefore, the correct answer is "In the nucleus."

    Which of these has a positive charge?

    • Electrons

    • Protons

    • Neutrons

    Correct Answer
    A. Protons
    Explanation
    Protons have a positive charge. They are subatomic particles found in the nucleus of an atom and have a relative charge of +1. Electrons, on the other hand, have a negative charge, while neutrons have no charge and are neutral.

    Rate this question:

  • 6. 

    Where are neutrons located?

    • Inside the nucleus

    • Outside the nucleus

    Correct Answer
    A. Inside the nucleus
    Explanation
    Neutrons are located inside the nucleus of an atom. The nucleus is the central region of an atom that contains protons and neutrons. Neutrons have no charge and are slightly heavier than protons. They play a crucial role in determining the stability and mass of an atom.

    Rate this question:

    Which charges are attracted to each other?

    • Protons and neutrons

    • Electrons and neutrons

    • Protons and electrons

    Correct Answer
    A. Protons and electrons
    Explanation
    Protons and electrons are attracted to each other because they have opposite charges. Protons have a positive charge, while electrons have a negative charge. According to the law of electric charges, opposite charges attract each other. Therefore, protons and electrons are attracted to each other. Neutrons, on the other hand, have no charge, so they do not interact with charged particles like protons and electrons.

    Rate this question:

  • 8. 

    In order for an atom to have an overall charge of 0. Which particles must be equal to each other?

    • Protons and electrons

    • Protons and neutrons

    • Neutrons and electrons

    Correct Answer
    A. Protons and electrons
    Explanation
    An atom has an overall charge of 0 when the number of protons (positively charged particles) is equal to the number of electrons (negatively charged particles). Protons carry a positive charge, while electrons carry a negative charge. Since opposite charges attract each other, an equal number of protons and electrons will balance out the overall charge of the atom, resulting in a charge of 0. Neutrons, on the other hand, have no charge and do not contribute to the overall charge of the atom.
