Which chemical property make the noble gases so unique?

Answer 1

Noble gases have completely filled orbitals. They generally have 8 valence electrons (helium has only 2) and have stable electronic configuration. Hence they are chemically inert and generally donot form compounds under normal conditions.

Answer 2

A greenhouse gas is a gas that has adsorption / emission bands in the infrared range. This usually means it has three or more atoms in its molecule, so it can store some heat energy briefly and alter its bond lengths occasionally.

Answer 3

There are six noble gases: helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe) and radon (Rn). Noble gases have completely filled orbitals / energy levels. They generally have 8 valence electrons (helium has only 2) and have stable electronic configuration. Hence they are chemically inert, generally donot form compounds under normal conditions and are unique.

Answer 4

Noble gases have completely filled orbitals. They generally have 8 valence electrons (helium has only 2) and have stable electronic configuration. Hence they are chemically inert and generally donot form compounds under normal conditions.

Answer 5

Gases can be compressed with little force used. Solids and liquids are virtually incompressible. If you were to set up an apparatus that allowed you to increase the pressure inside a vessel, it would be noted that the volume of the liquid and the solid would change very little, but the volume of the gas would decrease. This is due to the intermolecular forces between the individual molecules.

Answer 6

Gas describes the phase of matter that exists at or above its boiling point. The gas atoms or molecules have very little interaction with each other due to their low density and will fill up whatever volume the gas is contained in. Gases may be described by four properties: pressure, volume, number of gas particles and temperature.

Answer 7

gases have a less dense composition than liquids and solids so they can take up more space

Answer 8

they have completely filled valence orbitals / shells

Answer 9

they don't react with other elements

Answer 10

It floats
