Members of a group typically have similar properties and electron configurations in their outer shell. First ionisation energyThe minimum energy required to remove an electron from a neutral atom in its ground state. Unlike most of the actinides, the floating bar of elements that should be squeezed between actinium and lawrencium, which tend to have stable ions with a valency of 3 - that's to say, three electrons' worth of positive charge - nobelium's most stable ions are of valency 2. Nobelium's most stable isotope, nobelium-259, has a half-life of about 58 minutes. Mistaken-identity history, it's miscredited discoverer, its misleading and often mis-spelled name, all add to the aura of comedy and confusion around molybdenum.....and yet it's an element that's right at the root of life - not just human life, but pretty much all life on the planet: yes you'll find tiny amounts of it in everything from the filaments of electric heaters to missiles to protective coatings in boilers, and its high performance at high temperatures mean it has a range of commercial applications.
