Hint :The number of protons in the nucleus of an atom of a chemical element is known as the atomic number or proton number (symbol Z). A chemical element's atomic number is used to identify it. It is the same as the nucleus' charge number.

Complete Step By Step Answer:
The number of protons in the nucleus of an atom of a chemical element is known as the atomic number or proton number (symbol Z). A chemical element's atomic number is used to identify it. It is the same as the nucleus' charge number.
Any chemical element with an atomic number greater than 92 that is found above uranium in the periodic table is known as a transuranium element. Twenty-six of these elements have been discovered and named, with another twenty-six pending confirmation. The actinoid sequence includes eleven of them, ranging from neptunium to lawrencium. The transactinides are those with atomic numbers greater than 103. Both transuranium elements are radioactively decaying, with half-lives ranging from tens of millions of years to fractions of a second.
Since only two transuranium elements (neptunium and plutonium) have been discovered in nature, and those in trace quantities, the synthesis of these elements by nuclear reactions has been a valuable source of information about them. This expertise has aided scientists' interpretation of matter's fundamental nature, allowing them to predict the presence and essential properties of elements much heavier than those presently understood. According to current theory, the cumulative atomic number could reach 210 if nuclear instability does not prevent the presence of such elements. The transuranium group includes all of these still-unknown elements.
