  1. alkali metals
    any metal in Group 1A of the periodic table
  2. alkaline earth metals
    any metal in Group 2A of the periodic table
  3. anion
    any atom or group of atoms with a negative charge
  4. atomic radius
    one-half the distance between the nuclei of two atoms of the same element when the atoms are joined
  5. cation
    any atom or group of atoms with a positive charge
  6. electronegativity
    the ability of an atom to attract electrons when the atom is in a compound
  7. halogens
    a nonmetal in Group 7A of the periodic table
  8. inner transition metal
    an element in the lanthanide or actinide series; the highest occupied s sublevel and nearby f sublevel of its atoms generally contain electrons; also called inner transition element
  9. ion
    an atom or group of atoms that has a positive or negative charge
  10. ionization energy
    the energy required to remove an electron from an atom in its gaseous state
  11. metalloids
    an element that tends to have properties that are similar to those of metals and nonmetals
  12. metals
    one of a class of elements that are good conductors of heat and electric current; metals tend to be ductile, malleable, and shiny
  13. noble gases
    an element in Group 8A of the periodic table; thes and p sublevels of the highest occupied energy level are filled
  14. nonmetals
    an element that tends to be a poor conductor of heat and electric current; nonmetals generally have properties opposite to those of metals
  15. periodic law
    when the elements are arranged in order of increasing atomic number, there is a periodic repetition of their physical and chemical properties
  16. representative elements
    an element in an “A” group in the periodic table; as a group these elements display a wide range of physical and chemical properties. In their atoms, the s and psublevels in the highest occupied energy level are partially filled
  17. transition metal
    one of the Group B elements in which the highest occupied s sublevel and a nearby dsublevel generally contain electrons
