it depends on which element
is the element dangerous on its or is it generally stable
Some elements are stable on their own because they have a complete outer energy level. These elements are called noble gases. Hydrogen and Helium have a complete energy level with two electrons and all of the other elements are stable with eight. When an element doesn't have a complete outer energy level it is stable in a compound. This is because it is being combined with another element to complete it's energy level.
Gee, I sure wish I knew. It's a real pain in the 8===D trying to find logical explanations on Google. So, good luck with that question, whoever you are!
alnico is its own element
No diamond of its own accord is dangerous.
CO2 is a compound of carbon and oxygen, very stable, in a state of low chemical energy, with very little value.
Go to stable at the bottom of the page and click on make your own stable.
"The racehorse refused to leave the stable until she felt stable enough to stand on her own."
Mercury is a stable element at room temperature and does not decompose on its own. However, it can be broken down into other compounds through chemical reactions and processes. Mercury can also evaporate into the air as a vapor.
No
No, each element is unique to its own properties, so each element has its own box/number
because of the valence toms
