Which artificial element has been provisionally named seaborgium by American researchers in honour of Nobel Laureate Glenn T Seaborg?

Correct option is B

The correct answer is (b) Element 106.
· The artificial element seaborgium (symbol Sg) was named in honor of Glenn T. Seaborg, an American nuclear chemist who played a key role in the discovery of many elements and in the development of the actinide concept.
· Seaborgium was provisionally named Element 106 before it was officially given its name.
· The element was first synthesized in 1974 by a team of American scientists at the Lawrence Berkeley National Laboratory.
· Seaborgium is a synthetic element, meaning it is not found naturally and must be created in a laboratory through nuclear reactions. It is part of the transition metals and belongs to the d-block of the periodic table.
· Glenn T. Seaborg was awarded the Nobel Prize in Chemistry in 1951 for his work on the chemistry of transuranium elements. He is also credited with co-discovering plutonium and other elements.
Other Options:
· Element 103: Element 103 is lawrencium, which is named in honor of Ernest O. Lawrence, a physicist and Nobel laureate, not Glenn Seaborg.
· Element 90: Element 90 is thorium, a naturally occurring radioactive element, unrelated to Seaborg.
· Element 97: Element 97 is berkelium, named after the city of Berkeley, California, and not related to Glenn Seaborg.
