Question

Where do the radioactive elements tend to be located on the table.

Answer 1

Explanation:

Actinide Series of Metals

There are two rows under the periodic table: the lanthanide and actinide series. The lanthanide series can be found naturally on Earth. Only one element in the series is radioactive.

Answer 2

Actinide series of metals

• The actinide and lanthanide series are the two rows underneath the periodic table.
• On Earth, the lanthanide series is naturally occurring. The series only contains one radioactive element.
• The actinide series differs significantly. All of them are radioactive, and some are unnatural. Higher atomic number elements have only been created in laboratories.
• Around the globe, there are specialised labs that focus on conducting experiments on elements. The elements with lower atomic numbers are the result of some of these particle accelerators' pounding of atomic particles.
• Short-lived, high-atomic-number elements are created through the accumulation of additional components.
• Actinium (Ac) at atomic number 89 and lawrencium (Lr) at atomic number 103 make up the first fifteen elements that make up the actinide family.

Hence, radioactive elements tend to be located on the actinide series of the periodic table.
