Gaseous elements at room temperature? Group VIIIA (new Group 18) are called the noble gases. They used to be called the inert gases, but Neil Bartlett at UC, Berkeley showed that the noble gases could be made into compounds. Their reactivity is minimal. The noble gases are; Helium, Neon, Argon, Krypton, Xenon, and Radon. Radon is toxic, as it is radioactive. The other elements that are gases at room temperature are: fluorine, F2; chlorine, Cl2; oxygen, O2; nitrogen, N2; and hydrogen, H2. All these gases are diatomic. The halogens, fluorine and chlorine, are highly reactive, and very toxic. Oxygen and nitrogen are reactive, or can be made to react. They are not toxic per se. Hydrogen is, of course, very reactive. Hydrogen and nitrogen are not toxic, but they will suffocate you, as would the noble gases, if you ingested pure forms of them, and your oxygen supply was quenched.

Why are noble gases unreactive? What are the properties of noble gases? Noble gases are the quiet ones, they are the least reactive on the  periodic table. Noble gases have completely filled orbitals /  energy levels. They generally have 8 valen…ce electrons (helium has  only 2 valence electrons). Helium and neon have filled valence  shells. The noble gases have high ionization energies and stable  electronic configuration, so they have little tendency to gain or  lose electrons. Hence they are chemically inert and generally do  not form compounds under normal conditions.

The Noble Gases Some scientists used to call them the inert gases. It didn't really work because there are a few other gases that are basically inert but not noble gases. Nitrogen (N 2) might be considered an inert gas, but it is not a noble gas. The noble gases are another family of elements, and all of them are located in the far right column of the periodic table. For all of you budding chemists, the far right is also known as Group Zero (Group 0) or Group Eighteen (Group XVIII). This family has the happiest elements of all.

- Quick Answer. Noble gases are unreactive because their outer electron shells are full and therefore in their most stable state. Normally, elements react with one another because they have incomplete electron shells. They lose, gain or share electrons in order to gain a more stable electron configuration.

What do the noble gases have in common ? Rating Newest Oldest. Best Answer: The noble gases are a group of chemical elements with very similar properties: under standard conditions, they are all odorless, colorless, monatomic gases, with a very low chemical reactivity. They are placed in group 18 (8A) of the periodic table (previously known as group 0).

- Overview. Xenon is a noble gas. The term noble gas is used to describe the elements in Group 18 (VIIIA) of the periodic table. The periodic table is a chart that shows how chemical elements are related to one another. Noble gas suggests a group of elements that is too far above other elements to react with them.wo radioactive isotopes of xenon—xenon-127 and xenon-133—are used in medicine. These isotopes are used to study the flow of blood through the brain and the flow of air through the lungs. In most cases, the patient inhales the radioactive gas through a mask.

Why were the noble gases and their compounds discovered late? The noble gasses are inert or unreactive due to the fact that they all follow the rule of octet and have complete s²p^6 orbital arrangements in the highest energy level. Because most elements were discovered through their reactivity with other ele...

- The noble gases (arranged in order of increasing atomic weight) are helium, neon, argon, krypton, xenon and radon. Helium, neon and argon are the three noble gases with the lowest atomic masses. Helium, Neon, Argon. Helium, neon, and argon are the three lightest members of the noble  gases. Hydrogen is the lightest of all elements. According to the Periodic  Table, its atomic weight is 1.00794 u, even lighter than helium.

Noble gas This chemical series contains helium, neon, argon, krypton, xenon, and radon. The noble gases were previously referred to as inert gases, but this term is not strictly accurate because several of them do take part in chemical reactions.

What is Traumatic Brain Injury (TBI)? In small amounts, no. Freon is not toxic. But, it displaces oxygen. So, if you have a high enough concentration of freon in the air you breathe, you actually asphyxiate (lack …of oxygen to the brain) rather than being poisoned................

Learn about Noble Gases The gases are elements, which share similar properties. These properties include being monoatomic, colorless, odorless, being able to conduct electricity, and having low chemical reactivity. Noble gases include Helium, Neon, Argon, Krypton, Xenon and Radon.

Why Are Noble Gases Not Reactive? The six noble gases are helium, neon, argon, krypton, xenon and radon. While they are all highly unreactive, the heavier elements of the group do sometimes form compounds under certain conditions. The inner electron shells of these elements form a sort of shield around the nucleus, allowing the gases to be ionized with sufficient energy.

Noble gas Properties of the Noble Gases. The properties of the noble gases can be well explained by modern theories of atomic structure. The outer shell of valence electrons is considered to be “full” in noble gases, giving them little tendency to participate in chemical reactions. It has been possible to prepare only a few hundred noble gas compounds.

Noble gas The noble gases are colorless, odorless, tasteless, and nonflammable under standard conditions. They were once labeled group 0 in the periodic table because it was believed they had a valence of zero, meaning their atoms cannot combine with those of other elements to form compounds.or instance, argon, krypton, and xenon form clathrates with hydroquinone, but helium and neon do not because they are too small or insufficiently polarizable to be retained. Neon, argon, krypton, and xenon also form clathrate hydrates, where the noble gas is trapped in ice.

- Halogens are generally toxic, or even lethal, to biological organisms in their elemental forms. They tend to combine readily, and explosively, with metals, particularly with alkali metals. Fluorine is one of the most reactive elements in existence, attacking otherwise inert materials, such as glass, and forming compounds with the heavier noble gases.

Noble gas The noble gases make up a group of chemical elements with similar properties; under standard conditions, they are all odorless, colorless, monatomic gases with very low chemical reactivity. The six noble gases that occur naturally are helium, neon, argon, krypton, xenon, and the radioactive radon. Oganesson is variously predicted to be a noble gas as well or to break the trend due to relativistic effects; its chemistry has not yet been investigated. For the first six periods of the periodic tabl

- It is now known that these gases in fact do react to form chemical compounds, such as xenon tetrafluoride. Hence, they have been renamed to noble gases. However, a large amount of energy is required to drive such reactions, usually in the form of heat, pressure, or radiation, often assisted by catalysts.

- The most characteristic property of the noble gases is their extremely low chemical reactivity as compared to other elements. The noble gases all have a full set of electrons in their outer shells, so they have little tendency to trade electrons with other elements to form compounds.
