I've been druid for almost 10 years.... Never heard of this stone but you never know!
Clay Guida is most famous for mixed martial arts. Clay has never been knocked out in a fight and is ranked number five in the world in the featherweight category.
He never studied law he was almost struck struck by lightning and then decided he would become a monk but he did have a bachelor's and a masters degree
There are no maps made as a result of Apollo 13. The mission objectives of Apollo 13 were never completed, and the crew almost died.
Democrat... they never liked the Republican Union
Fluorine and francium are two elements that are never found as elements in nature due to their high reactivity. Fluorine readily reacts with almost all elements, while francium is extremely radioactive and decays quickly into other elements.
Noble gases or group 18 elements
Gold, for one, almost never combines.
If you mean react with, the answer is a lot. Lithium is one of the most reactive elements there is. To start with, it reacts violently to fluorine, chlorine, bromine, iodine, and astatine, the Halogens. It also reacts with hydrogen, oxygen, nitrogen, and carbon, hence why it's never found in nature in its elemental form. Its other major elemental reaction is with sulfur. Not surprisingly, there are a vast amount of compounds it also reacts with.

No, krypton is not typically used in fireworks. Common elements used in fireworks include sulfur, charcoal, and metals like strontium, barium, and copper which produce the different colors seen in fireworks displays.
Depending on the reason the horse gets hives and the sevarity in which the horse reacts, the time in which a horse can get hives can take from acouple min. to acouple hrs (almost never days).
There never was a Hurricane Teddy.
Nope. Never. We almost never get snow in the winter, and when we do, it almost never sticks.
I think your category answers the question... Sadly.. Justin Bieber.
Atoms of lithium, sodium, and potassium are highly reactive due to their single valence electron. As a result, they readily form compounds with other elements to achieve a more stable electron configuration. This is why they are almost never found alone in nature.
Alkali Metals, Alkaline-Earth Metals, and halogens are never found in nature uncombined.
