Seaborgium: The Artificial Element Honoring Glenn T. Seaborg

The question asks to identify the artificial element that American researchers provisionally named seaborgium, in honor of Nobel Laureate Glenn T. Seaborg.

Understanding the Naming Convention

Elements in the periodic table are sometimes named after famous scientists. Glenn T. Seaborg was a prominent American chemist, known for his significant contributions to the discovery and synthesis of several transuranic elements (elements with atomic numbers greater than 92). It is common practice to name elements in recognition of such influential figures in science.

Identifying Element 106

The element with atomic number 106 was synthesized in the early 1970s. Due to its synthetic nature and the recognition of Glenn T. Seaborg's work in element synthesis, researchers proposed the name seaborgium (symbol Sg) for this element.

• The provisional name was later confirmed and accepted.
• Seaborgium is classified as a transactinide element.
• Its atomic number is 106.

Relating to the Options

Let's look at the atomic numbers provided in the options:

• Element 103: Lawrencium (Lr)
• Element 106: Seaborgium (Sg)
• Element 90: Thorium (Th)
• Element 97: Berkelium (Bk)

Based on the established naming conventions and the history of element discovery, Element 106 is the artificial element that was provisionally named seaborgium in honor of Glenn T. Seaborg.

Conclusion

Element 106 is the artificial element recognized for being provisionally named seaborgium, celebrating the groundbreaking work of Glenn T. Seaborg in the field of nuclear chemistry.
