Correct.
Nobel gases are very unreactive.
they are very unreactive
Noble gases are very unreactive.
Noble gases are very unreactive chemical elements.
Unreactive
Noble gases are very unreactive.
Halogens are extremely reactive, noble gases are very unreactive. All noble gases are gases; only F and Cl are gases.
Because noble gases are unreactive the preservation in these gases of very precious documents and books is recommended; but this method is not largely applied because is very expensive.
Noble gases exist in nature in very low concentration and are very unreactive. These prevented their discovery earlier.
The full octet means the element is inert (non-reactive.)
Noble gases are very unreactive because the valence electron shell is filled.
The noble gases are the most unreactive family of gases. They have a full outer electron shell, making them very stable and unlikely to form chemical bonds with other elements. This includes gases such as helium, neon, argon, krypton, xenon, and radon.
