Term

Ionization Energy

Definition

The energy needed to remove the outer most electron.

  • forms cation (+)
  • The larger atomic radius, the easier it is to remove
  • atomic radius or the # of orbits determines strength
Term
Atomic Radius
Definition

The distance from the center of the nucleus to the outer most electrons.

  • the larger the atomic radius, the easier it is to lose the outer most electron
Term
Electron Negativity
Definition

The atom's ability to attract the electron within a bond.

  • The larger the atomic # or #of protons, the the more pull it has on the electrons
  • up and right increase
Term
What do the rows tell us on the periodic table?
Definition
  • where the outer electrons are
  • # of orbits/atomic radius
  • the higher the number, less ionization energy needed
  • from left to right on periodic table
