Across
- 6. Any of groups 13-16 in the periodic table; so named because they contain metals, nonmetals, and metalliods. These groups are often named for the first element in the family
- 8. Any electron in the outermost energy level of a natural atom. unpaired valence electrons are usually involved in chemical bonding
- 10. The law that states that the properties of the elements vary with their atomic numbers in a regular repeated pattern
- 11. An element in group 18 on the periodic table having eight valence electrons that fill the outer energy level
- 12. A row in the periodic table of the elements also called a series, the time interval for one complete cycle of periodic motion
- 13. A column of elements in the periodic table having similar valence electron arrangement, resulting in similar chemical properties; also known as a group
- 15. Any elements in groups 3-12 of the periodic table, typically having one or two valence electrons, which it easily loses, resulting in cations with charges of 1+ or 2+
- 16. An element that is typically dense, solid, ductile, malleable, highly conductive, and chemically reactive, especially in the presence of nonmetal elements. Located on the left end of the periodic table
Down
- 1. An element in group 2 of the periodic table, having two valence electrons that it tends to lose easily to become a 2+ cation, making it very reactive
- 2. An element that typically has four or more valence electrons and that does not exhibit the general properties of metals; located on the right selection that periodic table
- 3. Also known as a family
- 4. An element with characteristics between those of metals and nonmetals, also called a semi-conductor; located between metals and non-metals on the periodic table
- 5. An element from either of two rows usually placed below the periodic table; a ,ember of either the lanthanide or antinide series. it typically has two valence electrons
- 7. A table of the chemical elements arranged to display their periodic properties in relation to their atomic number
- 9. An element in group 1 of the periodic table, having one valence electronthat it can easily lose to form a 1+ cation, making it extremely reactive; the most reactive of all metals
- 14. An element in group 17 of the periodic table having seven valence electron, it easily gains an electron, forming a 1-anion
