The credit for the discovery of transuranic element goes to
Solution
To answer this question, you should recall the formation of the periodic table. The transuranium series refers to the elements with atomic numbers greater than 92, which is the atomic number of uranium. They are all man-made and radioactive.
Complete step by step answer:
There are 4 blocks in the periodic table: s-block, p-block, d-block and f-block. All of the s-block elements are metals. Usually, they are shiny, silvery, good conductors of heat and electricity, and lose their valence electrons easily. The p-block due to large accommodation power of p orbital has the biggest variety of elements and is the only block that contains three types of elements: metals, nonmetals and metalloids. d-block elements have properties that are between s-block elements and p-block elements properties. It consists of transition metals. The f-block elements are mostly radioactive. The block names were created to represent the quality of the spectroscopic lines of the atomic orbitals.
Transuranium elements refer to the elements after Uranium. The elements with higher atomic number have been only synthesized in laboratories. All of the transuranium elements are radioactive Trace amounts of neptunium and plutonium form in some uranium-rich rock, and small amounts are produced during atmospheric tests of nuclear weapons. All elements heavier than plutonium are entirely synthetic because of their instability it is difficult to find them in nature; they are created in nuclear reactors or particle accelerators.
The credit goes to Glenn Theodore Seaborg.
Note:
You should know the important rules governing the nomenclature of elements with atomic number more than 100 are: The name involves the numerical roots of required numbers from number 0-9 and then by adding the suffix ‘ium’. Roots for IUPAC nomenclature of elements:
Digit | 0 | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 |
---|---|---|---|---|---|---|---|---|---|---|
Root | nil | un | bi | tri | quad | pent | hex | sept | oct | enn |
Abbreviation | n | u | b | t | q | p | h | s | o | e |
