Question

Which of the following is an example of a transuranium element

Answer 1

  Elements with atomic number greater than  92(Atomic number of Uranium) are known as transuranium element.

Cm - Curium is a transuranium element as its atomic number is 96.

Answer 2

$\boxed{{\text{C) Curium, Cm}}}$ is an example of a transuranium element.

Further Explanation:

A tabular chart of the chemical elements in horizontal rows and vertical groups is termed as a periodic table. In this table, elements are arranged in the increasing order of their atomic numbers. The elements are arranged in such a way that those having similar properties are placed together. The creation of the periodic table has made the study of elements simpler and easier.

Transuranium or transuranic elements are the elements that have atomic masses greater than 92. All such elements are highly unstable and undergo radioactive decay. The element with atomic number 92 is uranium. So all the elements that come after uranium in the periodic table are known as transuranium elements. Since these elements show radioactivity, these are used in nuclear reactors and nuclear weapons in order to generate a large amount of energy.

The atomic number of samarium (Sm) is 62.

The atomic number of uranium (U) is 92.

The atomic number of curium (Cm) is 96.

The atomic number of thorium (Th) is 90.

Since the atomic number of curium (96) is greater than that of uranium (92), it is an example of transuranium elements. Therefore option C is the correct answer.
