LITH-I-UM
Let's start our look at the second row of the periodic table with lithium (Li). Lithium is the third element of the periodic table and was discovered in 1817 by a chemist named Arfvedson. You might find lithium in everyday objects, such as medicines and batteries.
This is the first metal encountered in the periodic table, and it is a silvery colored solid when purified. One thing to remember is that lithium is never found alone in nature. It is always bonded to other elements. Scientists use the letter pair "Li" to represent lithium in chemical equations. You might find it bonded to chlorine (Cl) from the other side of the periodic table in the molecule lithium chloride (LiCl).
Where can you find lithium?

Batteries You have batteries in many of your toys. In flashlights you need batteries. In your watch you probably have a battery. Well... Most of those batteries need lithium to work. Lithium is an important element in the way a battery makes electricity. |

Air Conditioners Next time it's really hot out and you're nice and cool inside, you should thank lithium. Lithium is used in air conditioning systems. You know that everyone uses air conditioning. That means everyone is using some lithium. |
