Helium.
The 107th element in the periodic table is Bohrium (Bh). It is a synthetic element, which means it is not found naturally and has to be created in a laboratory. Its atomic number is 107, and it is classified as a transition metal.
Rg stands for Roentgenium, which is a synthetic element with atomic number 111. It is a highly radioactive element that does not exist in nature and has only been created in the laboratory.
No, Tg is not a noble gas. It is the symbol for the element "Tennessine," which is a synthetic element created in a laboratory setting and is part of the halogen group on the periodic table.
Element number 113 (Nihonium) can be found in group 13 and period 6 of the modern periodic table. It is a synthetic element created in a laboratory and is highly reactive due to its configuration of valence electrons.
Ununbium, which is now known as Copernicium, is a synthetic element created in a laboratory and does not occur naturally. Its appearance is not well documented, but it is expected to be a silvery color based on its position in the periodic table.
element name before the name of inventor or the place whre discover this element because this are artificially made of people or experiment in laboratory!!
Dmitri Mendeleev
Mendelevium is an element on the periodic table with the atomic number 101. It belongs to the actinide series and is a synthetic element, meaning it is not found naturally but has to be produced in a laboratory. Mendelevium is named after Dmitri Mendeleev, the creator of the periodic table.
The 116th element on the periodic table is livermorium (Lv). It is a synthetic element that was first synthesized in 2000 by scientists at the Joint Institute for Nuclear Research in Russia and the Lawrence Livermore National Laboratory in California. Its atomic number is 116 and its symbol is Lv.
Technetium is not a naturally-occurring element; it was created in a laboratory.
Promethium is the element that is naturally found on Earth but is labeled as a laboratory-made element on the periodic table. Although traces of promethium have been found in uranium ores, it is primarily produced artificially through nuclear reactions.
Element 116 on the periodic table is Livermorium (Lv). It is a synthetic element that was first synthesized in 2000 by scientists at the Joint Institute for Nuclear Research in Dubna, Russia, and named after the Lawrence Livermore National Laboratory in the United States.
