Pretty much everything with an atomic number greater than 99. Nobelium, einsteinium, and rutherfordium are examples.
The Actinoids group contain all the synthetic elements. All the elements that have an atomic weight of 95 and above do not occur naturally. They are part of the actinoid elemental group.
