What was the last natural element discovered?
The last naturally occurring element to be discovered is tennessine, with the atomic number 117. It was first synthesized in 2010 by a team of Russian and American scientists. Tennessine is a highly unstable element that exists for only fractions of a second before decaying into other elements.
Why is uranium's element symbol U?
Because U is the first letter of the name uranium.
What is the heaviest element of group 2?
It is about Cf element. it is in the !8th group.
How many electrons does the heaviest naturally occurring element have?
Uranium, number 92 is the last of the naturally occurring elements and, of course, it has 92 electrons.
Why does uranium turn into plumbum at last?
Lead (Pb) is the ultimate element of the decay chain of uranium.And this lead isotope is not radioactive.
Which is the last metal in periodic table?
The last metal in the periodic table that is available in nature is uranium with atomic number 92.The newly discovered element, that doesn't have an official name yet, so scientists are calling it ununpentium, based on the Latin and Greek words for its atomic number, is having atomic number 115. The man-made 115 was first created by Russian scientists in Dubna about ten years ago.
What is the toxic radioactive metallic element that occurs in small quantities as a decay product of uranium?
All the decay chain isotopes are radioactive and toxic (excepting the last member which is non-radioactive but also toxic); you think probably to radium or polonium.
What is the highest numbered element in the periodic table to be natural?
Plutonium (atomic number 94) is the last element in the periodic table that may be found naturally, in trace amounts.
What is the last man-made element?
This element is ununoctium (Uuo): atomic number 118.
What is the second rarest element on Earth?
The second rarest element on Earth is unstable so it does not have a long life (22min.), but uranium is the rarest natural element and is the second heavist natural element. Actually, there are even rarer elements that last for less then fractions of a second. Some are so rare that they haven't even been discovered.
What is the element that forms last in nuclear fusion in stars?
Existing element is product of nuclear fusion, heavy element exist from over fusion and thus create high atomic mass substance. To answer what is the element that is form last in nuclear fusion in star is the same as asking what is the heaviest element occur or found in nature. Base on what is in periodic table. The heaviest element found naturally is around Uranium - Plutonium thus it could be considered the last product known in nuclear fusion in star. There are heavier element than Uranium and Plutonium but those are synthesize element. Nuclear fusion might go to element heavier than what is known in our periodic table but those substance may be unstable and decay over time until none of those exist.
Quantum number for uranium?
The quantum number for uranium is 92, which corresponds to its atomic number on the periodic table. Each element is uniquely identified by its atomic number, which indicates the number of protons in its nucleus.
