Technetium (element 43) was the first element to be discovered on Earth that was not found naturally in nature. It was synthesized in a laboratory by Italian scientists in 1937.
Technetium (element number 43) in 1937.
The element with an atomic number of 112 is called Copernicium. It is a synthetic, radioactive element that can only occur in a laboratory.
The element with the lowest atomic number among the transuranium elements is neptunium, with an atomic number of 93. It is the first transuranium element produced synthetically in a laboratory setting.
Nobelium is a synthetic element that is typically considered to be a solid at room temperature and pressure. However, since it is a synthetic element with limited availability, its specific physical state may vary depending on how it is prepared or handled in a laboratory setting.
Francium is a radioacive chemical element; francium is natural but also may be prepared in laboratory.
Actinium is a natural chemical element but also can be prepared in laboratory.
Actinium is a natural chemical element but also can be prepared in laboratory.
Californium (the isotope Cf-245) was prepared for the first time at Berkeley Radiation Laboratory, USA in 1950 by Glenn Seaborg, Stanley Thompson, Albert Ghiorso, Kenneth Street.
Chlorine was observed for the first time by Jan Baptist van Helmont near 1630 (in Holland) and prepared for the first time in laboratory by Carl Wilhelm Scheele in 1774 (in Sweden), but considered it to be a compound of oxygen. Sir Humphry Davy (in England) named it after identifying chlorine as a chemical element in 1810.
Fluorine is a naturally occuring element. Fluorine gas F2 is so reactive that it is not found in nature but has to be prepared in a laboratory. or chemical plant.
