Xenon And Krytron

Helium is rare because there are no biosynthetic ways of making it, and all the helium that we currently have in the world is a result of the decaying uranium and thorium

As said before, Krypton is used in some types of photographic flashes, some fluorescent bulbs, and its mixtures are used in signs to give them a greenish-yellow glow. It was also once used in measurements and is used in lasers for lab use.

In hardware it used to be used for the most part for electrical contacts however most now goes into chip resistors. In the substance business it is utilized as a part of the contacts for chlorine creation in electrochemical cells. Ruthenium is one of the rarest metals on the earth and is found as the free metal. Ruthenium is very contaminated and extremely hazardous to be around. Some of the compounds of ruthenium stain our skin and is reserved strongly in our bones. Ruthenium 106, one of its isotopes was used in testing the atmosphere of nuclear weapons, in the mid-1940s with a U.S. test and ended with a Chinese test. It’s one of those radionuclides that have and continue to produce improved cancer

● Gallium is used in electric circuits ● Gallium is in LED lights ● It can be used to make mirrors ● It is used in high temperature thermometers ● Also it is used in radiation medicine What is a Spectroscope?

Fluorine is the most reactive element of them all, it reacts to almost anything. It is so reactive that storing it is so difficult. It is a poisonous pale yellow gas. It is part of the non-metal and halogen family. Fluorine is so strong and dangerous that it can burn through human skin. In the periodic table it is element number nine(9). Fluorine has a mass of 18.9984032, it can be rounded to 19. It contains of 9 protons, 9 electrons and 10 neutrons. Fluorine is one of the rare elements that is able to attack diamond.

To develop background on the story I’d ask the following questions. What are your goals in life? What are your plans to achieve them? What do you think is important in order to achieve those goals? It’s important to have goals in life, it’s also important to know what to do to achieve them. In the book In Real Life, hardcore gamer Seth Gordon makes difficult choices between staying at home to develop a relationship with his talented photographer friend Hannah or pursue his dreams of celebrity competitive gaming in Korea.

To begin with, germanium is used in the manufacture of wide-angle camera lenses. The element gives special properties to the glass. Since, germanium has traits that are similar to silicon and tin, the semiconductor industry uses germanium is used to make transistors for use in electronic devices. Germanium is also used to create alloys and as a phosphor in fluorescent lamps. In other words, germanium is used to make camera lenses for electronic

As they are unreactive and do not readily combine with other elements, they are the easiest to extract and the earliest to be discovered and therefore were used long before any other metals.

Helium in the ancient days was a name use for the Greek god of the sun, Helios until three different scientist came across it in the nineteen hundreds. We find helium in blimps, birthday balloons, we also find helium in the earth’s atmosphere. Helium is also used in chemistry like scientific balloons, to insert shield in arc welding, and to pressurize the fuel tanks of liquid fueled rockets in supersonic wind tunnels, and for certain things in the laboratory.

Another thing found on “Google,” is that Germanium is used to make semiconductors, which is in our phones, and electronic devices, and is also in fluorescent lamps.

In 1805, the explosive properties of mercury fulminate were discovered; it was used in the percussion cap (invented 1815) to provide a surer,

My element is Argon and its symbol is Ar. Argon is the third most common gas that is found in the earth’s atmosphere. Argon is a noble gas that is also used to keep light bulbs from bursting. Argon is located in period 3 group 18. Argon is also used to make titanium and other reactive chemicals. Argon is an odorless, colorless gas. Argon is the 3rd most abundant gas. Argon has 8 protons, 8 electrons and 2 neutrons in its shell.

Helium is the second most abundant element in the universe, after hydrogen; however, it is rare on earth, primarily found mixed with natural gas trapped in underground pockets. Once helium is released it is so light it escapes the earth's atmosphere and cannot be recovered. At sea level, helium occurs in the atmosphere in the proportion of 5.4 parts per million. The proportion increases slightly at higher altitudes. About 1 part per million of atmospheric helium consists of helium-3, now thought to be a product of the decay of tritium, a radioactive hydrogen isotope of mass 3. The common helium isotope, helium-4, probably comes from radioactive alpha emitters in rocks. Natural gas, which contains an average of 0.4 percent helium, is the major commercial source of helium. By far the largest users of helium are agencies of the United States government.

Helium is a lighter than air gas. It has a 4.00260 atomic mass while air or oxygen has a 15.9994 atomic mass . According to Jefferson Lab editor Thomas Jefferson National Accelerator Facility “Helium, the second most abundant element in the universe, was discovered on the sun before it was found on the earth.” (2017,[online]). Oxygen is one of the most common gas and every living thing needs it to live. “Oxygen is written as

The element I decided to do was lead. Lead was used many years before and it is still used a lot today. Lead is still very useful and is found in many things that were used a long time ago and things we still use today. Lead is a very poisonous element that can really harm your skin and your body. Since lead is very toxic, it’s not recommended for children. Lead is also the heaviest of the carbon family.
