What element has the symbol 'Sg'?

The story behind the answer

Sg is the symbol for Seaborgium, element 106. The other choices have different symbols: Samarium (Sm), Strontium (Sr), and Selenium (Se). Seaborgium is a synthetic, short-lived transactinide element created in particle accelerators and does not occur naturally.

It’s named after Glenn T. Seaborg, a Nobel-winning American chemist who helped discover multiple transuranium elements and proposed the actinide concept of the periodic table. Fun fact: Seaborgium was named while Seaborg was still alive, a rare honor. Memory tip: “Sea-borGium” gives you the S and the g for Sg, and remember Se is already taken by Selenium.
