Answer 5

Is this your final answer? ^-^

Answer 6

yes

Answer 7

Correct! :D
If you look closely, the diagram contains:
Protons(+), Neutrons(No charge) and Electrons(-)
D is eliminated, because there is a difference for sure between Helium and Lithium.
Examining the graph closely, you can see that Lithium has MORE protons (3), neutrons(3) and electrons(3). Helium only has 2 protons, neutrons and electrons. Therefore, your answer is correct (C) ! :D
