O They have atomic numbers less than 92.
O They are all found in nature.
O They are all radioactive.

Answer 1

Transuranium elements are a group of highly unstable elements with atomic numbers greater than 92 that are not naturally found on Earth and are mostly radioactive.

Step-by-step explanation:

Transuranium elements are a group of elements in the periodic table that have atomic numbers greater than 92. These elements are not naturally found on Earth and can only be created through artificial means, such as nuclear reactions. They are also highly unstable and most transuranium elements are radioactive, meaning they emit radiation as they decay over time.
