Noble gas

Although Helium exists in the atmosphere of Earth in small quantities, it is one of the most common element in the universe. It is a rare gas on earth. Helium was first discovered by Pierre Janssen in the spectrum of the sun during an eclipse in 1868. It was shortly identified as an element and was named by the chemist Sir Edward Frankland and the British astronomer Sir Joseph Norman Lockyer. Helium has an atomic number of 2 and an atomic weight of 4.002602. Helium is represented by the symbol

The six Noble Gases are found in group 18 of the periodic table. These gases are stable and highly non-reactive. These gases are odorless and colorless, with very low chemical reactivity. The Noble gas Neon has the symbol of Ne and has the atomic number of 10. It was discovered in 1898 as one of the rare inert elements that remained dry in air. It was the

rapidly working, possibly fatal chemical that is present as an unscented white solid. When it is blended through water or an acid, sodium azide transforms quickly to a poisonous gas with a strong scent. Furthermore, it transforms into a poisonous gas (hydrazoic acid) when it meets solid metals although the scent of the gas may not be strong enough, up till now, to offer people enough cautioning of the hazard. Sodium azide is identified as the chemical originated in vehicle airbags. An electrical charge

to become a noble gas and period down the periodic table the easier it is to get rid of the extra electron, causing the alkali metals to become more reactive the further down the periods. To become a noble gas a halogen must gain an electron, the farther away the outer shell is from the nucleus, the more energy that is required for an electron to enter the shell. Halogens need one more electron to become a noble gas, while alkali metals need to donate an electron to become a noble gas. (Johnsonburg

Helium is the first noble gas on the Periodic Table. The symbol of Helium is “He”, and the Atomic number is 2. This element has a atomic mass of 4.00g. Helium was first discovered on the sun as a cooler gas by Sir William Ramsay. The noble gas helium was given it’s name referring to the Greek goddess “Helios”,on August 18, 1868. Helium is the second top element on planet Earth. Also, it is the gas that scientist found that was leaking from Mt. Vesuvius in Italy. The Gas that can give a weird reaction

The Periodic Table contains 118 elements, all different with shape, size, and what it’s made up of. Out of the 118, 3 were chosen and they will be discussed later in this paper. Those elements are Potassium, Sulfur, and Krypton. The first is Potassium. Potassium was first discovered and isolated by Sir Humphrey Davy, a Cornish chemist and inventor, in 1807. Potassium is highly reactive, but Davy isolated the element through a process what’s called electrolysis, a process by which an electric current

one was called Xenon, meaning “ The Alien One”, or “The Stranger.” Each of the new elements were unique by examining their spectrum. Then in 1910, Ramsay discovered Niton, or Radon in the radioactive emissions of radium, which was the last of the noble gases.      Since the gases that Ramsay discovered, had remarkable inertness, or completely unreactive, led to their use for special purposes. Helium

The standard state is a gas at which the temperature would be 298 K and it grasps the shape of air. Argon is a colorless, tasteless, odorless, and nontoxic gas since it is a noble gas and a gas has all those qualities. Argon makes up about 1 percent or 0.934 percent of the volume of the Earth's atmosphere and is the 3rd most created element in the Earth's atmosphere

Noble gases are the most stable elements of the periodic table. They have many qualities that make them unique to other elemental groups. Noble Gases have many important differences that should be noted when studying the periodic table; such as the number of valence electrons and location, their state of matter, and their reactivity. When studying noble gases you should be aware of what mainly sets them apart from the other elements of the periodic table; their valence electrons. They are unique

     Did you know that neon is a Greek word that means "new"? Neon is the element that I am most interested in. I chose to do neon because I found out what many uses it has in our daily life. Neon is the element that allows you to watch TV. Without neon we would never see the cool flashing signs outside of diners and bars. In my essay I am going to tell you about neon and its many uses. First, I'm going to tell you about the history and uses of neon. Neon was discovered
