Alkali Metals (7)

The Alkali Metals comprise the left-most column of the periodic table. As a rule, you wouldn't want any around the house in pure form, though as a compound they can be quite tasty. Hydrogen is an anomaly: It's traditional to put it in this column, but it really has very little in common with the rest. The others are soft metals that react violently with water to release hydrogen gas, which either bubbles off or spontaneously ignites depending on how far down you are on the table.
