1.	Sodium was made in 1807, iron was made in 1200 BC. Why such a huge time difference?
Answer» Answer: Sir Humphry Davy was ABLE to discover sodium (Na) in the LABORATORY. In 1807, he used electrolysis to remove this element from melted caustic soda. Electrolysis is a PROCESS that uses electric currents to create chemical changes. Another name for caustic soda is sodium hydroxide (NaOH). Although many people were using salt in the 1800s, it was difficult to extract sodium from it because this element is active and reacts easily with other elements. Davy found it was a metal. PURE sodium can go up in flames if it comes in contact with water, so he had to MAKE sure it was in a moisture-free environment.
