- - - - Leading zeros=NEVER COUNT
      - captive zeros=ALWAYS COUNT
      - Trailing zeros=ONLY COUNT if the number contains a .
      - Only zeros= the zeros after the decimal count
- - - - As you move downward on the periodic table, the atomic radius INCREASES because has more orbits. (Upward: the atomic radius decreases)
      - As you move from left to right across a period the atomic radius DECREASES because the larger the number of protons and electrons, the greater the attractive force. this causes the atom TO SHRINK. The orbits get closer and tighter to the nucleus
    - - As you move up and right on the periodic table, the first ionization energy increases because the outermost electron is closer to the nucleus, which is harder to remove because the attraction is greater
      - The smaller the atomic radius, the greater the ionization energy requires
      - The larger the atomic radius, the less ionization energy required because the valence electrons are farther from the nucleus and easier to remove
    - - As you move up and right on the periodic table, electronegativity increases due to the proximity of the shared electrons to the nucleas
      - The smaller the atomic radius, the greater the electronegativity because the attraction between the electrons and nucleus is greater.
