The fifth element of a state is international recognition, which involves other countries acknowledging a state's sovereignty and government.
The element with the lowest oxidation state on the periodic table is Francium.
A composition of an element is only fixed if it doesn't radioactively decay, chemically react, interact with a fundamental particle, and no external energy is introduced into the system. These four things happen quite a bit though and if they don't the element stays the same because it is at the lowest energy state it can obtain.
Element named after a US state: Californium. This is the only element named after a US state. But, there is also Americium. Americium is named after America.
how belief in the four element concept delayed the advancement of scientific thought in chemistry
