What is the definition of Ionic Radii?
The distance from the center of an ion's nucleus to its utermost electron.
What is hte definition of Ionization energy?
The energy needed to remove one of the atom's electrons
What is hte definition of Electron Affinity?
The energy change that occurs when an atom gains an extra electron.
