3. Mendeleev did not develop the periodic table entirely on his own; he inherited and built on knowledge that was handed down from many _____________ who spent their lives ______________ matter. In the early 1800s, about _____ elements were known, and although chemists knew that some of these elements acted in similar ways or had similar _______________, no one had found an overall, accepted ______________ in their _________________. The Matrix 4. Mendeleev’s periodic table presented a new paradigm, with all of the elements positioned within a logical matrix. The elements are arranged in a series of rows called “_______________,” so that those with similar __________________ appear in vertical ___________. Each vertical column is called a “______________,” or family, of elements. This instantly shows one set of __________________ when read up and down, and another when read from side to side. Some groups have elements sharing very similar properties, such as their _____________________ and their ________________. For example, each element has its own melting and boiling point, the temperatures at which it changes from a solid to a liquid and from a liquid to a gas. Another characteristic is how “______________” an element is, meaning how quick it is to join up with other elements. Scientists recognize how an element will react based on its _________________ on the table. 5. He arranged them in _____ that possessed similar properties.

Why are the elements placed in specific places on the Periodic Table? Periods are ________ that run from left to right. Elements in the same period have the same _________. Every element in the first period has ________ shell for its _______. Every element in the second period has __________ for its ___________. See the pattern? 5. Groups are _______________ that run from top to bottom. 6. The elements of a group have the same number of ____________ in their ___________ shell. 7. Every element in group one has _________ electron in its outer shell. Every element in group two has ___________ electrons in its outer shell. 8. Hydrogen is special because it can act like two groups, __________ and _________. 9. Hydrogen sometimes is ________________ an electron and sometimes it has an _____________ electron. 10. Although helium has only __________ electrons in its outer shell, it is grouped with elements that have ________________. 11. The green elements on this table are called ____________ elements. They each have two electrons in their outer shell.
