Now, If there are 6 protons in a nucleus that means there are 6 electrons on the outside, so A and D are the same element. However, you may be confused because of the different number of neutrons (6 and 7 or 7 and 8) this only means that one is and isotope of the element.
*Isotopes are atoms with the same number of protons but different number of neutrons. (Basically, same element different mass)

A census is a survey of a complete population and not just a small sample.
You can hold a census of your entire school, your whole city, or the entire state.
