Across
- 2. characteristics between those of metals and nonmetals
- 4. found to the left of the heavy stairstep line on the periodic table
- 5. set of elements in the same column on the periodic table, and have similarities
- 6. radius-the distance from the center of an atom's nucleus to the electrons in its outermost energy level
- 10. earth metal-often added to alloys, homogeneous mixtures that contain at least one metal, to make them stronger
- 11. tendency to gain this electron makes them highly reactive
- 13. measure of an element's ability to attract and hold electrons when bonded to other atoms
- 14. electron-the electrons in the outermost energy level of a neutral atom
- 17. law-states that the properties of the elements vary in a periodic way with their atomic numbers
- 18. set of elements in the same column on the periodic table, and have similar physical and chemical properties
Down
- 1. group-contain metals, nonmetals, and metalloids, and so they are called mixed groups
- 3. metal-most of these elements have one or two valence electrons
- 6. metal-the most reactive of all the metals and always found as parts of compounds
- 7. transition metals- get their name from their proper placement-between the transition metals in the periodic table
- 8. gas-very useful for creating a nonreactive environment
- 9. have four or more valence electrons and do not exhibit the general properties of metals
- 12. table-a table of the chemical elements arranged in a way that displays their periodic properties in relationship to their atomic number
- 15. dot notation-consists of the element's chemical symbol surrounded by the atom's valence electrons
- 16. row on the periodic table
