noble elements
Yes, it is possible.
In order to fill their outer most shells and become more stable atoms form BONDS.
Because it is a very stable element. It is one of the "Noble Gases" which are the most stable elements known.
The strongest and most stable bonds involve carbon (C) to carbon bonds. C in sp, sp2, and sp3 hybridization, that is single, double and triple bonds, are the most stable.
No, it is exothermic because they form bonds to become more stable spontaneously
Atoms or molecules do chemical reactions to be stable, noble gasses are already stable, so they do not react with other molecules to form chemical bonds
Yes, atoms of copper and iron can generally form stable bonds with transition elements. Copper and iron are both transition elements themselves and can form stable bonds with other transition elements. The stability of the bonds will depend on factors such as the electronegativity and bonding properties of the specific elements involved.
Four
The noble gases are unreactive because their valence shells are full, making them stable.
The element carbon.
The reason why there are so many carbon compounds is because carbon is very stable.
