HOW HIS WORKED…
Put elements in rows by increasing atomic weight.
Put elements in columns by the way they reacted.
He left blank spaces for what he said were undiscovered elements. (Turned out he was right!)
He broke the pattern of increasing atomic weight to keep similar reacting elements together.

1a) What are the 7 Alkali Metals that will easily bond with Fluorine?
Lithium, Sodium, Potassium, Rubidium, Cesium, Francium
b) What other elements in the Halogen Family with bond with any of the Alkali Metals?
Chlorine, Bromine, Iodine and Astatine
c) Will any of the Elements in the Alkaline Earth Metals bond with any of the Halogens? Explain.
Because all of the A.E.M.s have 2 valence electrons, any two of the halogens would bond with any of them.
