What is the most common element in the sun
hydrogen
The Sun contains about 92% hydrogen and 8% helium, with just a tiny bit of the other common elements we find on Earth. Compare that to Earth, where the most common elements are oxygen, magnesium, silicon, and iron.
What is the most rare element in the universe
Astatine
Astatine is the rarest naturally occurring element. The total amount of astatine in the Earth's crust (quoted mass 2.36 × 1025 grams) is estimated by some to be less than one gram at any given time.
What is the 2nd most abundant element in the universe
Helium
Helium is the second-most abundant element in the universe, after hydrogen, and accounts for about 25 percent of the atoms in the universe.
What is the 2nd rarest element on Earth
Osmium

Has element 119 been made
Ununennium, or element 119, is a predicted chemical element. Its symbol is Uue. Ununennium and Uue are substitute names made by the IUPAC, (meaning "one-one-nine-ium" in Latin) until permanent names are made. Ununennium is the element with the smallest atomic number that has not been created yet.

What is the rarest element in the universe
Astatine
Astatine is the rarest naturally occurring element.
Is gold the rarest element on earth
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.
Has element 123 been discovered
As of February 2021, no attempt has ever been made to make element 123.
Does element 120 exist
Unbinilium, also known as eka-radium or element 120, is the hypothetical chemical element in the periodic table with symbol Ubn and atomic number 120.
How rare is gold
According to Fedortchouk, the average concentration of gold in Earth's crust is "very, very low," at 4 parts per billion.
Which is the rarest of rare element on earth
The rarest element on the Earth is Astatine(At).Its atomic number is 85.It is obtained by the decay product of heavier elements.The decay of Uranium and Thorium gives Astatine.t 1 / 2 for Astatine is 8.1 hrs.Atomic mass for this element is 210.It is a radioactive element.
Does element 119 exist
Ununennium, also known as eka-francium or element 119, is the hypothetical chemical element with symbol Uue and atomic number 119. Ununennium and Uue are the temporary systematic IUPAC name and symbol respectively, which are used until the element is discovered, confirmed, and a permanent name is decided upon.
How was element 111 created
Roentgenium has no known biological role. A man-made element of which only a few atoms have ever been created. It is made by fusing nickel and bismuth atoms in a heavy ion accelerator.
Is element 119 real
Ununennium, also known as eka-francium or element 119, is the hypothetical chemical element with symbol Uue and atomic number 119.
Can element 137 exist
Element 137 is Untriseptium (Uts), it is a hypothetical element and its name is temporary as it hasn't actually been discovered. The current name literally means 137. Many believe if ever discovered it will be named after the physicist Robert Feynman as he predicted the periodic table would end at element 137.
Are diamonds rarer than gold
The average concentration of gold in Earth's crust is 'very, very low,' at 4 parts per billion. In its elemental form, gold is significantly rarer than diamonds.
How much gold is left on Earth
We do know that gold makes up about four parts per billion of the earth's crust. What we don't know, however, is precisely how much gold is still out there. The WGC estimates that there are 54,000 tonnes of “below-ground gold reserves” waiting to be mined.
What was the 1st rare-earth elements
The first rare-earth mineral discovered (1787) was gadolinite, a black mineral composed of cerium, yttrium, iron, silicon, and other elements.
Does element 126 exist
Unbihexium, also known as element 126 or eka-plutonium, is the hypothetical chemical element with atomic number 126 and placeholder symbol Ubh.
Has element 120 been found
No unbinilium atoms were identified. Neither element 119 nor element 120 was observed.
What is rarest than gold
platinum
If translated into numbers, platinum—for all of its known deposits—is considerably more rare than gold and is the rarest metal of all.
How many diamonds are left in the world
Some 142 million carats of diamonds were estimated to have been produced from mines worldwide in 2019. Major producing countries include Australia, Canada, the Democratic Republic of Congo, Botswana, South Africa, and Russia. Worldwide reserves are estimated to be some 1.2 billion carats.
Who owns the most gold
The United States holds the largest stockpile of gold reserves in the world by a considerable margin at over 8,100 tons. The U.S. government has almost as many reserves as the next three largest gold-holding countries combined (Germany, Italy, and France).
Is gold unlimited on earth
But despite its popularity, gold is actually a finite scarce resource. In the mining industry, if you manage to extract a twenty-eighth of an ounce (1 gram) of gold from 1 ton of earth then you can consider yourself lucky.
