Question

difference between monotonic and polyatomic atoms with example

Answer 1

Monatomic ion. ... If an ion contains more than one atom, even if these are of the same element, it is called a polyatomic ion. For example, calcium carbonate consists of the monatomic ion Ca2+ and the polyatomic ion CO32−. A type I binary ionic compound contains a metal (cation) that forms only one type of ion.

Example- Any of the elements of the periodic table in ionic form. H+, Li+, Be2+, O2-, F-, Fe2+, Fe3+ and so on. Could be added that some elements don’t form monatomic ions because of the high energy required to do so.
