Noble gases have a full _________ _____ and are therefore very stable.
valence shell
Noble gases are not very _________.
reactive or inert
Amount of energy needed to remove the most loosely bound electron from a neutral gaseous atom.
IONIZATION ENERGY
It is the distance between nuclei of identical atoms bonded together. (Basically tells the size of a neutral atom).
ATOMIC RADIUS
It is the measure of its attraction for electrons when bonded to another atom.
ELECTRONEGATIVITY
electrons in the outer energy level of an atom
VALENCE ELECTRONS
Electrons can gain or lose energy and move to different levels.
PRINCIPLE ENERGY
LEVELS
The distance from the nucleus to the outer principle energy level of the ion.
