Answer 1

I know this is probably late but do you know the difference between an element and a compound?

An element is something on the periodic table and most times is a pure substance while a compound is usually made up of two or more elements.

So take a look at your answer choices and ask yourself, which of these is a stand alone substance? Which of these only has one set of a capital letter + a lowercase, or just a capital letter.

(This is my way of leading you to the answer without blatantly telling you)
