Introduction
Imagine if you fell asleep on your chemistry book one day during Mr. Sanders class and woke up in a completely different world. Within this strange world are horses that can talk, a lion that can not only talk but he is also friendly enough to allow you to ride on his back and wolframs. In the book, The Chemy Called Al by Wendy Isdell, Julie shares what it is like to experience all different kinds of adventures evolving around horses who can speak, friendly lions and wolframs. The adventures of Julie traveling through the different worlds is characterized by time spent with the periodics, Chemylion and trying to understand what is going on with the X-Ray machines and who was responsible.

The ancient Romans used lead to make water pipes which some are still being used today. Lead is sometimes discovered free in nature but normally found in ores. It’s high density helps make it a useful shield against X-Ray and gamma ray radiation. It's used within nuclear reactors and X-Ray machines. In The Chemy Called Al when Julie turns on the T.V. to see if it works, she quickly finds out that the volume works but the picture doesn't. Shortly after the news broadcast comes on and alerts the community that there has been a malfunction at the local hospital with the X-ray machines. This bothered Julie so she started to do her own research in her chemistry …show more content…
Primarily, tin is found in the mineral cassiterite. Tin is extracted by roasting cassiterite in a furnace with carbon. Tin is corrosion resistant and it’s used as a pro time coating for other metals. Tin’s atomic number is fifty, and its atomic weight is 118.710. Tin’s boiling point is 505.08 K or 449.47 °F. Tin is a solid at room temperature.
Since ancient times, Antimony is sometimes found freely in nature. Nicolas Lémery was the first person to scientifically study it and its compounds. He published his findings in 1707. Antimony is a poor conductor of electricity and heat. Very pure antimony is used to create specific types of semiconductor devices, like infrared detectors. To increase lead’s durability, people use antimony that is alloyed. Ancient Egyptians used it for black eye make up in the form of stibnite.
