Periodic Table

4. any of the three phases in which an element can exist; solid (s), liquid (l), gas (g)
8. elements of the periodic table are periodic functions of their atomic number
9. elements that have zero or one property/characteristic of a metal; located above/to the right of the staircase
10. elements that have all four properties/characteristics of a metal; located under/to the left of the staircase, except for Hydrogen (H)
11. take the shape of their container and have definite volume; only 2 elements exist as liquids at STP: Br, and Hg
12. all elements located in Group 1 on the periodic table except hydrogen
14. a measure of the relative tendency of an atom of an element to attract or gain electrons; the “desire” to gain electrons; electronegativity is based on a scale from 0.0-4.0
15. all elements located in Group 17 on the periodic table; have high electronegativities

1. the tendency for an atom of a given element to gain or lose electrons when interacting with an atom of another element
2. all elements located in Group 18 on the periodic table; inert (do not tend to react with atoms of other elements); have a full valence shell
3. vertical columns on periodic table
5. have definite shape and definite volume; most elements are solids at STP
6. elements that have two properties/characteristics of metals; located along the “staircase,” except for aluminum (Al)
7. elements with similar properties; group 1, 2, 17, and 18 on periodic table
9. character nonmetals are NOT malleable (shatter upon being hit with a hammer), NOT ductile, do NOT have luster (dull), and do NOT conduct electricity
13. have no definite shape and fill their container; at STP this includes H, N, O, F, Cl, & all of group 18 (the noble gases)
