Questions

  1. 1.

    Which statement correctly describes the relative charges, relative masses, and locations of protons, neutrons, and electrons within an atom?

    • A) Protons have a relative charge of +1 and a relative mass of 1, neutrons have a relative charge of 0 and a relative mass of 1, both residing in the nucleus, while electrons have a relative charge of -1, negligible mass, and occupy space outside the nucleus.
    • B) Protons have a relative charge of +1 and negligible mass, while electrons have a relative charge of -1 and a relative mass of 1 located inside the nucleus alongside neutral neutrons.
    • C) Neutrons have a relative charge of -1 and a relative mass of 1 in the nucleus, while protons and electrons both have positive charges and reside in energy levels outside the nucleus.
    • D) Protons and neutrons both have a relative charge of +1 and reside outside the nucleus, whereas electrons have a relative charge of 0 and make up the dense central nucleus.
