The thallous compounds are used in various industrial applications.
Thallous is derived from the Greek word "thallos" (θάλλος), meaning a young shoot or twig. The suffix "-ous" indicates possessing or full of. Therefore, thallous refers to something that is characterized by or related to young shoots or growth.
Imagine a young shoot or twig ('thallos') that is full of life and growth — that's what 'thallous' means.
