They have 8 valence electrons, and are thus "happy" with their electron configuration. The other elements (with exceptions) want to form ions with noble-gas-like electron configuration.

They are less reactive. They have filled electronic shells at the K, L, and M levels, corresponding to principal quantum numbers 1, 2, and 3. It used to be thought that they were completely unreactive. Then, in the 1960's, chemists at Purdue discovered that Xenon could react with fluorine to produce XeF6. And XeF6 could react with water to make XeO3. Some noble gases still do not react: He, Ne.

The noble gases (or inert gases) are not poisonous whereas halogens (other gases) are. The other elements (alkali metal, alkali earths and transition metals) are solid and have a range of properties. Alkali metals (Li, Na, K) are soft and easily oxidised. Alkali earths (Be, Mg, Ba) react with steam. Transition Metals are dense, have a high melting point, lustre, good conductors etc.

They have "filled" outermost shells of electrons and therefore do not in most natural circumstances form chemical compounds. Similarly, much more so than other elements in most circumstances, they partition strongly into a gas phase (as monatomic gas), so that they are called the "noble gases" (also, "inert gases").

For it to alter right into a noble gas it would could have the comparable proton numbers as a noble gas. Do you recommend it has the comparable electron extensive style as a noble gas? a million. confident, the features might selection. 2. it somewhat is going to likely be a negatively charged fluorine atom... i'm seventy 5% confident i'm real, yet i did not one hundred% get what you have been asking, so i could be incorrect...

They have 8 electrons in their Valence shell making them very stable and of no interest in combing with other elements the only exeption is Xe it has an isotope that will bond with other elemnts

They have 8 valence electrons, so they dont mix with other elements to make compounds. You see, elements with valence electrons under 8 mix with other elements so they can have at least 8 valence electrons so they are stable.

All I remember from school ( long time ago) is that they are more stable than regular gases and that they don't react in the same way than them. Sorry

they dont bond with other elements, thus are "noble"
