Question

and isotopes review quiz
which of the following statements are true regarding these atoms:
each atom has the same number of protons
each atom represents an isotope of 1 atom
each atom represents an ion of 1 atom
each atom has a varying number of neutrons

Explanation:

Isotopes are atoms of the same element with the same number of protons but different numbers of neutrons. From the image, the number of protons (purple spheres labeled 'p') is the same in both atoms, and the number of neutrons (blue spheres labeled 'n') is different. This indicates they are isotopes of the same element. Ions are atoms that have gained or lost electrons, and there is no indication of that here.

Answer:

Each atom has the same number of protons
Each atom represents an isotope of 1 atom
Each atom has a varying number of neutrons
