Single displacement occurs when one element replaces another in a compound, with metals displacing metals and nonmetals displacing nonmetals. The document provides examples, including hydrogen replacing tungsten and chromium displacing hydrogen in compounds. It also references cases of synthesis and oxidation-reduction.
