These elements are called transuranic elements.
There are currently 118 elements in the periodic table, with elements beyond uranium being synthetic and not found in nature.
Elements beyond uranium (atomic number 92) are not typically included in the alien periodic table as they are synthetic and not naturally occurring on Earth. This includes elements such as neptunium, plutonium, and beyond.
Element 193 is not assigned in the periodic table as elements beyond uranium (element 92) are not naturally occurring and have been synthesized in laboratories.
Yes, scientists have created synthetic elements in laboratories through nuclear reactions. Examples include elements beyond uranium (element 92) on the periodic table, such as neptunium, plutonium, and others. These synthetic elements are typically unstable and have short half-lives.
Yes, certain elements in the periodic table, such as elements in the third row and beyond, can have an expanded octet, meaning they can have more than eight valence electrons in their outer shell.

All the elements after uranium exist but excepting neptunium and plutonium (present in the earth crust only in ultratrace concentrations) they are man made.
Elements beyond uranium (atomic number 92) are not typically included in the alien periodic table as they are synthetic and not naturally occurring on Earth. This includes elements such as neptunium, plutonium, and beyond.
Element 193 is not assigned in the periodic table as elements beyond uranium (element 92) are not naturally occurring and have been synthesized in laboratories.
Some elements are not naturally occurring because they are created in laboratories through nuclear reactions or particle accelerators. These synthetic elements do not have stable isotopes and decay rapidly, making them difficult to find in nature. Examples include elements beyond uranium on the periodic table.
Transuranic elements: Np, Pu, Am, Cm, Bk, Cf, Es, Fm, Md, No, Lr, Rf, Db, Sg, Bh, Hs, Mt, Ds, Rg, Uub, Uut, Uuh, Uuq, Uup, Uuo.
These elements are typically referred to as transuranium elements, located beyond uranium on the periodic table. Examples include elements like fermium, mendelevium, and einsteinium, which are artificially produced in laboratories due to their large atomic sizes and unstable characteristics.
Synthetic elements are typically made in laboratories through nuclear reactions or particle accelerators. These processes involve bombarding lighter elements with particles in order to create heavier, unstable elements that do not occur naturally. Some examples include creating elements beyond uranium in the periodic table.
Elements with atomic masses greater than uranium are typically produced in supernova explosions, where high-energy processes enable the fusion of heavy nuclei. This process can lead to the creation of transuranic elements such as neptunium, plutonium, and beyond. Additionally, elements beyond uranium can also be artificially synthesized in particle accelerators through nuclear reactions involving target nuclei.
Some man-made elements are stable, while others are not. Stability of an element depends on its structure and nuclear properties. Elements beyond uranium on the periodic table tend to be less stable, with some being highly radioactive and decaying quickly.
