What is the most expensive element?
franciumThe most expensive natural element is francium.
Although francium occurs naturally, it decays so quickly that it cannot be collected for use.
Only a few atoms of francium have been produced commercially, so if you wanted to produce 100 grams of francium, you could expect to pay a few billion U.S.
dollars for it..
What is the rarest man made element?
AstatineAstatine is the rarest element on Earth; only approximately 25 grams occur naturally on the planet at any given time.
What is the strangest element?
The most weird and wonderful elements in the periodic tableKrypton (Atomic number: 36)Curium (Atomic number: 96)Antimony (Atomic number: 51)Copernicium (Atomic number: 112)Bismuth (Atomic number: 83)
What is the rarest thing in the universe?
Now astronomers have spotted a bizarre star that may prove to be one of the rarest objects ever, with maybe as few as five or six of them in the galaxy. The object in question is known as J005311, located in the constellation Cassiopeia about 10,000 light-years from Earth.
Is wood rarer than diamond?
but wood is a complex organic structure and compared to its diamonds is simple. In the whole universe, wood is rarer than diamonds. Trees can give you oxygen and it is one of the major member of our ecosystem and after they die they gives us wood. So woods are more valuable than diamonds.
What is the hardest thing in the universe?
The Hardest Known Substance In the Universe Is Something Called “Nuclear Pasta”
What is the smallest thing in the universe?
As far as we can tell, quarks can’t be broken down into smaller components, making them the smallest things we know of.
Is plutonium man made?
Plutonium is a radioactive metallic element with the atomic number 94. It was discovered in 1940 by scientists studying how to split atoms to make atomic bombs. Plutonium is created in a reactor when uranium atoms absorb neutrons. Nearly all plutonium is man-made.
Are actinides man made?
Actinides are the 15 elements with atomic numbers from 89 to 103. They are named after the first element in the series, actinium. The actinides group includes mostly man-made elements with only a few exceptions such as uranium and thorium.
What is the most rarest element on earth?
element astatineA team of researchers using the ISOLDE nuclear-physics facility at CERN has measured for the first time the so-called electron affinity of the chemical element astatine, the rarest naturally occurring element on Earth.
What elements do not exist on Earth?
Technetium. The first element that was synthesised, rather than being discovered in nature, was technetium in 1937. This discovery filled a gap in the periodic table, and the fact that no stable isotopes of technetium exist explains its natural absence on Earth (and the gap).
