The chemical elements with atomic numbers of 93 or greater are known as the transuranic (or transurarium) elements.

There is no such word as transculanic. The whole series of 14 elements from No. 89 Ac is called the actinide series of rare earths. Beyond At. No. 100 are sometimes called transfermium. Transuranic is also used.

They are called the transuranic elements because they are “beyond uranium” on the periodic table—that is, they have an atomic number higher than that of uranium.
Atomic number is the count of protons in the atoms of a particular element. The protons in an atom determine what element that atom is: atoms of a particular element may have different numbers of neutrons (an element with a certain number of neutrons is an *isotope* of that element), but they always have the same number of protons.

Transuranic.
It's because Uranium is no. 92. So any element with an atomic number greater than 92 is Transuranic.
