  47. 47. What happens to atomic radius (size) moving down a group? WHY? A Unit 5 for 300
  48. 48. What happens to atomic radius (size) moving down a group? Down a group the radius increases because each new period requires the use of new orbitals (1s to 2s to 3s…etc)

  50. 50. What happens to the atomic radius (size) moving across a period to the right? The size of an atoms gets smaller moving across a period because the number of protons increase, pulling the electrons in the orbital in tighter

  52. 52. Is the trend for ionization energy the same or the opposite of the trend for atomic radius? WHY? The trend for ionization energy is OPPOSITE ; as the size (radius) of the atom increases it is easier to remove an electron- therefore the energy required to form an ion is lower
