Amphid salts

Amphid salts was a name given by Jons Jacob Berzelius in the 19th century for chemical salts derived from the 16th group of the periodic table which included oxygen, sulfur, selenium, and tellurium.[1] The term received some use in the early 1800s but is now obsolete.[2] The current term in use for the 16th group is chalcogens.
