This page will present statements comparing samples of two elements. You are to determine if the statement is correct or incorrect. For example,
"A 3.4 g sample of Fe has a larger volume than a .45 mole sample of Cr"
Using only your periodic table and reasoning, determine the correct response and click on the appropriate circle. You should avoid using a calculator, though that may not always be possible. The questions will appear below the tables when you press the "New Question" button. Use the "Correct" and "Incorrect" dots below the table to input your selection. Results and running totals will appear in the table, immediately. 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.
