노벨륨은 다이너마이트를 발명한 알프레드 노벨의 이름을 땄다. +2 산화 상태를 선호하는 유일한 악티늄족 원소이다.

노벨륨 개요

A preference for the +2 oxidation state distinguishes nobelium from every other member of the actinide series, which otherwise favours the +3 state. The anomaly follows from the filled 5f subshell of its [Rn] 5f14 7s2 configuration, which is stable enough that the element gives up only its two 7s electrons in most reactions. Nobelium takes its name from Alfred Nobel, the inventor of dynamite, and holds atomic number 102 with a relative atomic mass of 259.0 and an electronegativity of 1.3. It is a solid under standard conditions. The element is synthetic, and its chemistry has been established through aqueous tracer studies conducted on vanishingly small samples.
