From about 50 years the chemistry of noble gases is more and more better known; many compounds are known and the future is promising.
Scientists have observed that certain conditions can cause inert gases like xenon, krypton, and argon to form compounds with other elements. Additionally, experiments have shown that inert gases can react with elements under extreme conditions, such as high pressure and temperature. These observations challenge the traditional view that inert gases are completely unreactive.
Inert Gases
Noble gases are gases and 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 called inert gases.
The Noble gases were known as inert gases because it was believed that they were completely unreactive. This is no longer true as scientists have discovered compounds containing noble gas elements.
Chemically inert Have completely filled valence orbitals
Noble gases are inert gases because of a completely filled valence shell,hence they need not to satisfy their valency.
Noble gases have completely filled electronic configuration. and hence they are generally chemically inert.
Because they are chemically inert (or noble) due to the presence of completely filled orbitals.
Because they are chemically inert (or noble) due to the presence of completely filled orbitals.
Noble gases have completely filled valence orbitals and are hence stable or chemically inert.
Noble gases have completely filled outer most shell. They are chemically inert and exist as monoatomic species.
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 and generally donot form compounds under normal conditions.
