__ Mystery of Matter 2 __ Name............................... What was seen through a spectroscope? How were elements distinguished in Mendeleev's time? What do families of elements have in common? What did “even changes between elements in both rows and columns” indicate? Which was more important to Mendeleev, an element's atomic weight or properties? What did Mendeleev suggest about blank spaces in his table? What was the single biggest revision to Mendeleev’s table? What type of Honeymoon did the Curies take? What was Marie’s secret weapon? What could the Curies measure better than anyone in the world? What element could make air a better conductor? What property of matter was Marie studying? What did the readings from pitch blend indicate? What did new spectral lines indicate? What was the energy coming out of a radioactive element a sign of?

Which did Mendeleev think was correct:
 * That the properties of the elements are determined by atomic weights and the properties very in a regular periodic way going across the table.
 * That the atomic weights of elements are determined by properties and the atomic weights are similar going down the table.
 * That periodic weights are determined by atomic properties and these weights reduce in a regular way going across the periodic table.
