Beryllium is a rare, but naturally occurring element. It is mined in ore form and is refined for purity.
Argon is not "mined". It is produced by fractional distillation of air--air is liquefied, then boiled in stages.
Berylium is a non metal element. Atomic mass of it is 9.
Berylium is a metal element. There are 4 electrons in a single atom.
Copper. Some gold is also produced.
No, nuclear energy is not mined. Nuclear energy is produced by splitting atoms in a process called nuclear fission, which releases energy. The fuel used in nuclear reactors, such as uranium or plutonium, is mined from the earth.
Einsteinium is not mined as it is a man-made element produced in nuclear reactors by bombarding heavier elements with neutrons. It is typically produced in very small quantities and is not commercially mined due to its radioactive nature and short half-life. Once produced, einsteinium can be isolated and purified through various chemical processes.
Chlorine itslf is not mined. The materials used to produce chlorine (NaCl) is mined. Chlorine is produced by electrolytic reaction of a chloride solution (e.g. NaCl) in a process involving a diaphragm cell or a mercury cell. The mercury cell process has been largely discontinued because of its associated loss of mercury to the environment.
