Ununennium, also known as eka-francium or element 119, is the hypothetical chemical element with symbol Uue and atomic number 119.
Astatine is a chemical element with the symbol At and atomic number 85. It is the rarest naturally occurring element in the Earth's crust, occurring only as the decay product of various heavier elements. All of astatine's isotopes are short-lived; the most stable is astatine-210, with a half-life of 8.1 hours.
Scandium (Sc)
First discovered in 1879, scandium (atomic number 21) was named for Scandinavia by chemist Lars Fredrik Nilson.
Fusion requires several milligrams of the target element, and producing enough einsteinium (element 99) to make element 119 is impossible with today's technology.
Einsteinium is an element with a famous name that almost no one has heard of. With 99 protons and 99 electrons, it sits in obscurity near the bottom of the periodic table of chemical elements, between californium and fermium.
Osmium, rhodium and iridium are probably the rarest metals found in the Earth's crust with average concentrations of 0.0001, 0.0002 and 0.0003 parts per million by weight respectively.
Because electrons have non zero rest mass, they cannot exceed the vacuum speed of light according to Einstein's theory of relativity. Thus, atoms with Z > 137 cannot exist.

Since element 123 is unknown, it has no biological role.
Hofmann's original colour scheme (carbon = black, hydrogen = white, nitrogen = blue, oxygen = red, chlorine = green, and sulphur = yellow) has evolved into the later color schemes.
Astatine: The chemical element astatine has the atomic number and the symbol . It belongs to group and period of the periodic table. It is the rarest naturally occurring element in the crust of the Earth and only appears as a decay product of several other heavier elements.
Astatine is the rarest element on Earth; only approximately 25 grams occur naturally on the planet at any given time. Its existence was predicted in the 1800s, but was finally discovered about 70 years later.
Uranium was discovered in 1789 by German chemist Martin Heinrich Klaproth. It is the heaviest naturally occurring element in the universe and is naturally radioactive. Its nucleus is unstable, so the element is in a constant state of decay, seeking a more stable arrangement.
Radium is an extremely rare element on Earth. It is found in uranium ores. It takes about 7 tons of ore just to produce a single gram of radium.

In short, the answer is no. The statement 'diamond is an element' is misleading as carbon itself is an element. While a diamond is composed of 100% of carbon with no other elements involved, it is not an element but simply an allotrope of the element carbon.
Livermorium is a synthetic element with the symbol Lv and an atomic number of 116. It was first reported by Russian scientists from Dubna (Joint Institute for Nuclear Research) in 2000. Its former name was ununhexium and the name Livermorium name was adopted by IUPAC on May 31, 2012.
A synthetic element is one of 24 known chemical elements that do not occur naturally on Earth: they have been created by human manipulation of fundamental particles in a nuclear reactor, a particle accelerator, or the explosion of an atomic bomb; thus, they are called "synthetic", "artificial", or "man-made".
Neutronium is the hypothetical element zero, with no protons in its atomic nucleus. Neutronium is the name of a theoretical element with atomic number 0 and symbol Nu that consists entirely of neutrons. Other names for neutronium are neutrium and neutrite.
Final Element of Periodic Table is Element N 137.
The least expensive elements are Carbon, Sulphur, and Chlorine which are cheap by their mass. Hydrogen, Oxygen, Nitrogen, and Chlorine are the least expensive elements by their volume in the atmospheric pressure.
Plutonium is a radioactive element that can be used for research and nuclear applications. It's worth about $4,000 per gram (although you can expect various regulatory agencies to take a close look at you if you start accumulating it).
