Try dragging the magic crystal to move it. The order of questions are different every time! The magic crystal will ask you one of these questions: What is the name of element # ? What is the symbol for element # ? What is the atomic mass of element # ? For example, if the atomic number is 21, then the name would be Scandium, the symbol would be Sc, and the atomic mass would be 45. Note that the atomic mass is rounded to the nearest whole number. If you get it wrong, the crystal will give you the answer to take note of for later. After thirty questions have been asked and answered, the crystal will generate a letter grade based on your score. The grades from best to worst are: ~ A: 91% - 100% ~ B: 81% - 90% ~ C: 71% - 80% ~ D: 61% - 70% ~ F: 0% - 60% It celebrates if you get 100%. If you choose to try the second half, the same thing will happen but afterwards the scores are added to make a total.
This is for me and my classmates to use, but you can try it too if you like. The left variable column represents the correct answers and the right variable column represents the incorrect ones. The first row in each column represent the first half of the quiz. The second row in each column represent the second one. The last row in each column represent the addition of the two other variables in its column. Can you get a perfect score without looking the answers up online? That's for you to find out.
