what class of elements includes all of the elements that are gases at room temperature
70224f16c449e286ea56d8f5e6675fbc
- The elements that are gases at room temperature include hydrogen. They also include all the inert or noble gases, which are those elements in Group 18: helium, neon, argon, kr…ypton, xenon and radon. We also know that the halogens fluorine, chlorine and bromine are gases at room temperature (20°C). That leaves nitrogen and oxygen as the last of the elements that are gases at room temperature. All of these elements are nonmetals or halogens or inert gases. LAUGH OUT LOUD.

- Any element can be a gas when it is heated up enough. Argon, helium, and oxygen are 3 examples of elements that are gasses in room temperature. Water, for example, can be a ga … s when it is heated to 100 degrees and turns into vapor.

- In their elemental form at room temperature, the Group 8A elements are all colorless, odorless, monatomic gases. The Group 8A elements have a full octet of eight valence electrons in their highest-energy orbitals (ns 2 np 6), so these elements have very little tendency to gain or lose electrons to form ions, or share electrons with other elements in covalent bonds.

- All noble gases have the maximum number of electrons possible in their outer shell (2 for Helium, 8 for all others), making them stable. Helium Neon Argon Krypton Xenon Radon This website is copyright © 1996-2012 Yinon Bentor. The six noble gases are found in group 18 of the periodic table. These elements were considered to be inert gases until the 1960's, because their oxidation number of 0 prevents the noble gases from forming compounds readily. All noble gases have the maximum number of electrons possible in their outer shell (2 for Helium, 8 for all others), making them stable. 1  Helium.

The Noble Gases and Halogens The noble gases. This group contains helium, neon, krypton, xenon and radon. They are different to elements belonging to other groups due to their resistance to form compounds. The reason behind their unreactivity is their full outer shells that give stability to the atoms.

What is the only non metal which is a liquid at room temperature?? Report Abuse. Gallium (31Ga) is the only metal, except for mercury, caesium, and rubidium, which can be liquid near room temperatures; this makes possible its use in high-temperature thermometers. It has one of the longest liquid ranges of any metal and has a low vapour pressure even at high temperatures.

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.

What are noble gases and where on the periodic table are they? Noble gases are elements that have all possible electron positions in the outer, or valence, shell filled. This makes them chemically non-reactive. They are found in group 18 on the periodic table (far right edge) of elements: Helium (He), Neon (Ne), Argon (Ar), Krypton (Kr), Xenon (Xe), and Radon (Rn).

Noble gas For the first six periods of the periodic table, the noble gases are exactly the members of group 18 of the periodic table. It is possible that due to relativistic effects, the group 14 element flerovium exhibits some noble-gas-like properties, instead of the group 18 element ununoctium. Noble gases are typically highly unreactive except when under particular extreme conditions.

Noble gases The noble gases are the six elements that make up Group 18 of the periodic table: helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), and radon (Rn). At one time, this family of elements was also known as the rare gases. Their present name comes from the fact that the six gases are highly unreactive; they appear almost noble—above interacting with other members of the periodic table.
