Which statement describes the location of 5 protons and neutrons in an atom of helium?

March 3, 2018

  1. Which statement describes the location of 5 protons and neutrons in an atom of helium?

    1.   Protons and neutrons are in the nucleus.

    2.  Protons and neutrons are outside the

      nucleus.

    3.   Protons are outside the nucleus, and neutrons are in the nucleus.

    4.   Protons are in the nucleus, and neutrons are outside the nucleus. 

Answer and Explanation:

There are three subatomic particles students should be familiar with: protons, neutrons and electrons. Both protons and neutrons are located inside the nucleus making it positively charged and therefore choice 1 as the correct answer choice.

Electrons, on the other hand, are located outside the nucleus and are negatively charged.
