Any element; neptunium can form himself a critical mass.
Neptunium forming the critical mass can explode.
Neptunium itself is an element, the simplest form of matter.
Neptunium is a metal, and therefore it can in theory form all the usual kinds of compounds that metals form; it could combine with oxygen and form neptunium oxide. However, neptunium is a radioactive element with a very short half-life, therefore it does not stick around long enough to engage in chemical reactions, or even if it did, the resulting compound would also exist only for a very brief period of time.
using a needler continuously on an enemy to make a pink explosion!
silocon and calcium
no it does not
u wil need to make water and that it
Combine the "Tools" element with the "Tree" element.
Oxygen is simply an element. Nitrogen is another element. They can combine to make a variety of compounds, but no element is "based" on another.
The elements that must combine to make propane are C and H, using symbols. These are carbon and hydrogen, respectively.
This is chlorine (Cl).
