  1. 2. earth metal- an elemnt in group 2 of the periodic table having 2 valance electrons that can easily lose to form +2 cation making it extremly reactive
  2. 4. element that typically has four or more valance electronsand that does not exhibt the general properties of metals
  3. 7. an element with characteritics between those of metals and non metals
  4. 10. radius -the distance from the center of an atoms nucleus to its outermost energy level
  5. 11. an element that is tipcally dense ,solid,ductile,malleable, highly conductive, and chemical reactive
  6. 13. metal -an element in group 1 of the periodic table, having one valance electron that can easily lose to form +1 cation making it extremly reactive
  7. 16. see family.
  8. 17. metal-any element in group 1-3of the periodic table, typically having one or two valance electron which it easily loses, resulting in cations with charges of 1+ or 2+
  9. 18. group- any groups of 13-16 in the periodic table so named because they contain metals

  1. 1. electron- -any electron in the outermost energy level of a nuetral atom. unparied valnce electrons are usally involved in chemical bonding
  2. 3. law - the law that states that the properties of the elements vary with their atomic numbers in a regular, repeted pattern
  3. 5. gas- an element of group 18 on the periodic table having 8 valance electrons that fill the outer energy level
  4. 6. - a measure of an elements ability to attract and hold electrons when bonded to other atoms
  5. 8. A colum of elements in the periodic table having similar valance electrons arrangment, resulting in similar chemical properties also known as a group
  6. 9. dot navigation- a representation of an atom consiting of its chemical symbol with surrounding dots represtinting its valance electrons
  7. 12. an element in group 17 of the periodic table having 7 valance electrons, it easliy gains electrons -1
  8. 14. table- A table of the chemical elements arranged to display their periodic properties in relation to their atomic numbers
  9. 15. a row in the periodic table also called a series
