Final answer:
The element found in refrigerants that contributes to ozone depletion is chlorine.
Step-by-step explanation:
The element found in refrigerants that contributes to ozone depletion is chlorine. Chlorine atoms from chemicals such as chlorofluorocarbons (CFCs) can react with ozone molecules and break them down, resulting in ozone depletion. CFCs used to be widely used in refrigerants, air conditioning systems, foams, and aerosols, but there is now a global effort to reduce their use due to their harmful effects on the ozone layer.
