Answer: If it has ions, it is an electrolyte
Explanation:
Let's start by explaining that electrolytes are compounds that contain charged particles or<u> ions</u>, which can be cations (positive ions) or anions (negative ions).
So, it is this composition that makes an electrolytic material conduct electricity.
In this sense, the way to identify if a material is an electrolyte or not, is knowing whether it is composed of ions or not.
Gamma rays are the highest energy EM radiation and typically have energies greater than 100 keV, frequencies greater than 1019 Hz, and wavelengths less than 10 picometers.
