Which is it?
This page will present questions describing samples of two elements and ask you to choose which sample meets a specified criterion. For example,
"Which will have a larger volume, 3.4g sample of Fe or a .45mole sample of Cr"
Using only your periodic table and reasoning, you should determine the correct answer and click on the circle in front of the correct response. You should avoid using a calculator, though that may not always be possible. The questions will appear in the top frame when you press the "New Question" button and results and running totals appear in the main frame, below.Since there are only two possible choices, the answer is displayed immediately after your response and you only get a single attempt at any question.
