Which one of the following elements is used as a timekeeper in atomic clocks?

A) Potassium B) Caesium
C) Calcium D) Magnesium
 
Answer & Explanation Answer: B) Caesium

Since 1967, the official definition of a second is 9,192,631,770 cycles of the radiation that gets an atom of the element called caesium to vibrate between two energy states.
