Question

the picture shows a model of a helium atom and a model of a lithium atom. which of the following statements is true about the lithium and the helium atoms? a. helium has more protons, neutrons, and electrons. b. there is no difference between helium and lithium. c. lithium has more protons, neutrons, and electrons. d. lithium is much smaller than helium.

Explanation:

By looking at the atomic models, lithium has more protons (3 in lithium vs 2 in helium), more neutrons (4 in lithium vs 2 in helium), and more electrons (3 in lithium vs 2 in helium). Helium has an atomic number of 2 and lithium has an atomic number of 3.

Answer:

C. Lithium has more protons, neutrons, and electrons.
