3. The answer is B. 11. This is because there are the same amount of electrons and protons in an atom, and since there are 11 protons, there are 11 electrons.
5. The formula H2O means that there are 2 hydrogen atoms (because the 2 is after the H), and 1 oxygen atom, so the answer is C.
Hope this helps!
