The first atoms of seaborgium (Sg) were identified in 1974.
The longest-lived isotope of Sg has a mass number of 266.
(b) Atoms of Sg are very unstable, and it is therefore
difficult to study this element’s properties. Based on the
position of Sg in the periodic table, what element should it
most closely resemble in its chemical properties?
