A blue circle labeled proton and A overlaps a pink circle labeled neutron and C. The overlap is labeled B.

The Venn diagram compares protons with neutrons. Which shared property belongs in the region marked "B"?

Is negatively charged
Has mass of 1 amu
Orbits the nucleus
Is positively charged

In the Venn diagram comparing protons and neutrons, the shared property that would belong in the region marked "B" – the area of overlap between the blue circle (proton) and the pink circle (neutron) – is has mass of 1 amu.

Both protons and neutrons are types of nucleons, they both have a mass approximately equal to 1 atomic mass unit (amu).

The other options are specific to either protons or neutrons:

  • "Is negatively charged" refers to electrons.
  • "Orbits the nucleus" also refers to electrons.
  • "Is positively charged" specifically refers to protons.

So, "has mass of 1 amu" is the appropriate shared property for the region marked "B".
