radioisotope etymology

Etymology and Meaning:

"Radioisotope" is a compound word derived from two roots:

• Radio-: from Latin "radius," meaning "ray" or "beam," referring to radioactive emissions.
• -isotope: from Greek "iso-" (equal) and "-topos" (place), meaning "occupying the same place."

Origin:

The term "isotope" was coined by British physicist Frederick Soddy in 1913. He proposed using the suffix "-tope" to denote elements with the same atomic number but different atomic weights. In 1919, the term "isotope" was officially adopted by the International Union of Pure and Applied Chemistry (IUPAC).

The Term "Radioisotope":

The term "radioisotope" was first used in the early 20th century, after the discovery of radioactivity by Marie Curie and others. It refers to a specific type of isotope that undergoes radioactive decay, emitting particles such as alpha, beta, or gamma rays.

Meaning:

Radioisotopes are atoms of an element that have the same atomic number (i.e., the same number of protons) but different numbers of neutrons. This difference in neutron number results in different atomic masses for the isotopes of the same element. Radioisotopes are unstable and undergo radioactive decay, spontaneously transforming into different elements or isotopes.
