Across
- 7. You can predict a lot about chemical _3_ of an element if you know where it is on the periodic table
- 8. Metallic elements are typically _10_ and are good 11_ of heat and electricity
- 9. The 7 horizontal rows are called _29_
- 10. On a square, above the chemical symbol is the _6_ of the lement, and below the symbol are the full name of the element, and its _7_
- 11. Each row corresponds to a different _30_
- 12. What makes the periodic table really invaluable is its use as a(n) _2_ tool.
Down
- 1. Atoms are listed (on the periodic table) in order of increasing _19_, as you read the periodic table from left to right,top to bottom.
- 2. Each element is represented by one _4_ on the periodic table, with one or two-letter chemical _5_
- 3. The _1_ is the most powerful tool chemists have for organizing chemical information
- 4. Each element has a unique atomic number-that's the number _20_ in the necleus of the atom
- 5. If you arrange elements by atomic number, a pattern emerges. There is a _21_, or a repeating of certain characteristics
- 6. A vertical comumn of lements is called a(n) _26_ or a family
