What its position in the table tells us

Seaborgium sits in period 7, group 6 and the D block. That location is useful because neighbouring elements often share trends in valence electrons, oxidation states and bonding behaviour.

Worth remembering
Seaborgium is synthetic, very short-lived and studied atom by atom in nuclear-physics laboratories
