5. Mercury Mercury is found in nature. It is found in the walls of the ancient mines in Almaden, Spain. The use of mercury is for light bulbs, batteries, and thermostat’s. Mercury is so dense that if you place a piece of lead in a salad bowl of mercury, it would float. Mercury has 80 protons and 121 neutrons and 80 electrons. Reece Arnold and 1-1 5

6. Gold It has 79 protons and electrons and 118 neutrons. It was discovered in circa 3000 B.C. Au comes from the Latin word aurum(gold) The uses for gold is in electronics, Jewelry, and coins. Reece Arnold: 1-1 6

7. Titanium It has 22 protons and 26 neutrons and 22 electrons Titanium was found in 1791 Information Reece Arnold: 1:1 7

8. Platinum Platinum has 78 protons and 117 neutrons and 78 electrons Information Reece Arnold: 1-1 8
