Potassium, Carbon, Xenon, and Silicon

Potassium
The chemical symbol for Potassium is K. It has one valence electron and it is an unstable element. It is in the group of 1A and on period 4. It is an  metal and is a solid. It has 19 protons and electrons. The mass number is 39.098. Because of its high reactivity, potassium is not found free in nature. It is formed by supernovas via the R-process and occurs on Earth dissolved in seawater and in ionic salts.Potassium was first purified in 1807 by Sir Humphry Davy from caustic potash (KOH) via electrolysis. Potassium was the first metal to be isolated using electrolysis.

Carbon

The chemical symbol for carbon is C. It has 6 protons and electrons. Its mass number is 12.001. It is a nonmetal and also is a solid. It is located in group 4A and period 2. It has 3 valence electrons in its outermost shell. Pure carbon exists free in nature and has been known since prehistoric time. Carbon comes from the Latin word for "charcoal". It is the fourth most abundant element in the universe. Pure carbon can damage lung tissue because it is non toxic.



Xenon

The chemical symbol for Xenon is Xe. It has 54 protons and electrons. It is located in group 8A, also called noble gases and period 5. It has 8 valence electrons and it is a stable element. Its mass number is 131.293 and is also a nonmetal. Xenon is found in the atmosphere at levels of approximately one part in twenty million. It was discovered by Sir William Ramsay and  M. W. Travers in 1898

Silicon

The chemical symbol for Silicon is Si. It has 14 protons and electrons which also is the atomic number. The atomic mass of the element is 28.086. It is located in group 4A and period 3. It is an unstable element and it is a metalloid. Silicon is a solid element. It was discovered by Jons Jacob Berzelius in 1824. It is the second most abundant element in the universe and makes up 25.7% of the earth's crust.  Silicon is an important ingredient in steel.



Research the Gases used in "Neon" signs to Produce the Gases.

Neon signs contain many gases to produce light. Mercury is a gas that gives off the ultraviolet light. another one is Argon which produce the light-blue color in a neon sign. Another one is Helium which gives off the pinkish-red glow. Next is Xenon gas can be used to produce a bright lavender light. The last one is Krypton which produces the characteristic color of yellow-white light. Not just Neon is the only gas that gives the Neon sign to produce light but also many other gases helps produce the light as well.

Describe nuclear energy and its practical application as an alternative energy source and its potential problems

Changes can occur in the structure of the nuclei of atoms. These changes are called nuclear reactions. Energy created in a nuclear reaction is called nuclear energy.

So nuclear energy is energy released by reactions within atomic nuclei, as in nuclear fission or fusion. An alternative energy source can be renewable energy. It is energy which is generated from natural sources (sun, wind, rain, tides) and can be generated again and again as and when required. It is good because to generated anything it can be used such as the wind to help generate energy etc. The potential problems is that what happens when there is no wind and sunlight? Then you will have no energy to generate things.

Difference Between Fission and Fusion

Nuclear fission is the splitting of a nucleus into smaller, more stable fragments accompanied by a large release of energy. Nuclear fusion is the process of binding atomic nuclei into a single layer and more stable nucleus. Nuclear fusion reactions are capable of releasing very large amounts of energy.

Difference between alpha, beta, and gama radiation

Alpha is made up of alpha particles. Each alpha particle contains two protons and two neutrons and it has a +2 charge. Alpha deflected toward is a negative charged plate. Beta is  deflected toward the a positive charged plate. It is made up of beta particles that consist fast moving electrons. Gamma radiation is the thrid common radiation. It is also called gamma rays. Gamma rays are high-energy radiation that possess no mass. Since they possess no electrical charge, they are not deflected by electric or magnetic fields.

The Recycling Factory

Dear Mr. Smith
You must separate the materials in order for you to dump the recycled. First, you get a powerful magnet to pick up the steel can. Then you dump all of the materials to the other large tank of water. The density of the water was is 1.0g/cm cubed. When you drop the materials, the milk jugs will float since the densities of the milk jugs  are under 1.0g/cm cubed. The milk jug's density is 0.95g/cm cubed. After that, you pour the suger water to the water making the density of 1.5g/cm cubed. The soda bottles density is 1.4 g/cm cubed. So that will make the soda bottles float on the sugar water. Since the aluminum soda can's density is 2.7g/cm cubed, it will sink down in the water because the concentrated sugar water's density is 1.5g/cm cubed. It will sink because the density of the aluminum soda cans's density is greater than the concentrated sugar water. So the nets willl pick up the aluminum soda cans. This experiment will work to solve the solution of separating the recycling materials.

Why Chemistry Is The Most Important Science?

Chemistry is important because the science that deals with the composition and properties of substances and various elementary forms of matter. It tells you pretty much anything like chemical reactions, matter, chemicals, etc. Without chemistry there will be no such thing as food, sunlight , and yourself because everything relates to chemistry. Chemistry should be called chemistry because since everything relates to chemistry just might as well called chemistry, everything. Chemistry is so important in today's science.
