Question

The elements which emit natural radioactivity are known as ___. *

​

Answer 1

The elements which emit natural radioactivity are known as Radioactive elements.

Explanation:

Radioactive elements are made up of atoms whose nuclei are unstable and give off atomic radiation as part of a process of attaining stability.

The emission of radiation transforms radioactive atoms into another chemical element, which may be stable or may be radioactive such that it undergoes further decay.

Answer 2

Answer:

Elements that naturally exhibit radioactivity are known as radioactive elements.

Explanation:

• The discovery of radioactivity in 1896 by Henri Antoine Becquerel (1852-1908) opened the door to a whole new group of unstable elements.
• Radioactive elements are those that decay due to instability and over time decay into one of three types alpha, beta, and gamma.
• Every matter around us is made up of elements or different types of atoms. While these atoms are too small to see, if you dissect any matter like an object or organism, ultimately everything is made up of these tiny particles.
• Some matter breaks over time, these are radioactive elements, which means that over time they decay, releasing energy and becoming different elements.
• Examples of radioactive elements are uranium, radium, radon, thorium etc.
