Define Octet Rule and introduce Lewis dot symbols.
Dots represent valance electrons.
Relate relative size of cations compared to their neutral atom counterparts and between relative size of anions compared to their neutral atom counterparts. Predict the relative ionic radii from a set of ions. Electronegativity-The ability of an atom to attract electrons to itself. Linus Pauling developed the 0-4 scale. Identify the trend in the periodic table for increasing electronegativity.
