Neon: A Gas in Neon Signs.

Neon is one of the noble gases on the Periodic Table. The other five Noble Gases are Helium, Argon, Kryton, Xenon, and Radon. The lights that produce a large array of colors are made by these gases. Neon creates a different color than the other gases because the electron emission spectrum.

The Electron Emission Spectrum is a spectrum of frequencies of electromagnetic radiation that is emitted from the element's atom when they return to a lower energy state.

Since each element has a different amount of electrons, the colors vary.

Helium: Red

Neon: Yellow-gold, orange

Argon: blue

Kryton: purple

Xenon: white

Radon: yellow, orange-red

Nuclear Chemistry

Alpha, Beta, and Gamma Rays

Alpha- the radition that was reflected toward the negatively charged plate.

Beta-the radiation that was reflected toward the positively charged plate.

Gamma- High-energy radition that possess no mass.

Difference Between Fusion and Fission

Fission- a nuclear reaction in which the nucleus splits into smaller particles

Fusion- the process by which two or more atomic nuclei join together

Production of Nuclear Energy

Nuclear energy is the controlled use of nuclear reactions to release energy for various reasons. It's pros are that it's used in medicine and as reuseable energy. A con is that it's a highly dangerous energy and it causes a large amount of pollution such as in the air and water.

Letter to the Recycling Factory

To whom it may Concern,

The city of Westminster hired me to separate various substances from a complied pile. The items were ground up into a fine powder and can not be phyically separated. The items and their densitys are:
aluminum soda cans: 2.7 g/cm^3
steel cans: 5.7 g/cm^3
milk jugs: .95 g/cm^3
soda bottles: 1.4 g/cm^3

First, separate the steel from the powder. Use the magnets hanging above the conveyor belt to attract the steel from the pile. Since steel is magnetic, it'll shift through the pile and stick onto the magnets.

Second, put the remaining powders in the large tank provided by Mr. Smith. As the powders sink, one will float up. The floating powder is the crushed milk jugs. Then, you'd use the net to skimming nets to pull the milk jug powder out.

Third, I used the the concentration of sugar water to make one type of powder to float. Since the sugar water has a density of 1.5 g/cm^3, the soda can powder will float at the top. Once they rise to the surface, use the skimming nets to obtain the powder.

Lastly, drain the sugar water from the remaining powder which is the aluminum can powder. And finally you have finished.

Why Chemistry is an Important Science?

The definition of chemistry is the chemical reaction matter undergoes. Without chemistry, we wouldn't be able to understand how our bodies digest food, how some foods are made, how metabolism gives us energy. These are just a few examples of how chemistry is so important in our lives.
