What is the first discovered element?

The ‘first’ chemical element Phosphorous (P) was the first chemical element to be discovered after the ancient times by German alchemist Hennig Brand in 1669. At the time, Brand was trying to create the philosopher’s stone, a legendary alchemical substance that was thought to turn metal into gold.

What was the first element?

Hydrogen is the simplest atom possible. It has only one proton in the nucleus, which is orbited by only one electron. It is the only element that does not have any neutrons.

What is the 30th element?

Represented in the periodic table as Zn, zinc is a transition metal, grouped with cadmium and mercury. With the middling atomic number 30, it has five stable isotopes of atomic weight from the dominant zinc 64 to zinc 70, plus an extra 25 radioisotopes.

Is plutonium a natural element?

Plutonium and other so-called transuranic elements are considered by most to be man-made elements. This element has usually been considered synthetic because it is produced most efficiently in nuclear reactors. But in the strictest sense, the answer to the question is yes, plutonium does occur naturally.

What is the oldest element?

Do we know all the elements?

Although there are elements we have not yet created or found in nature, scientists already know what they will be and can predict their properties. For example, element 125 has not been observed, but when it is, it will appear in a new row of the periodic table as a transition metal.

Is it legal to own depleted uranium?

Contrary to some of the answers, it is not illegal AFAIK to own or buy depleted uranium. It has been used in civilian applications such as counterweights for aircraft or in the medical field (it actually provides excellent shielding against radioactive materials).
