Monatomic ion

Monatomic ion

A monatomic ion is an ion consisting of one or more atoms of a single element (unlike a polyatomic ion, which consists of more than one element in one 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. A type II ionic compound contains a metal that forms more than one type of ion, i.e., ions with different charges.

Common type I cations
Hydrogen H+
Lithium Li+
Sodium Na+
Potassium K+
Rubidium Rb+
Caesium Cs+
Magnesium Mg2+
Calcium Ca2+
Strontium Sr2+
Barium Ba2+
Aluminum Al3+
Silver Ag+
Zinc Zn2+
Common type II cations
iron(II) Fe2+ ferrous
iron(III) Fe3+ ferric
copper(II) Cu2+ cupric
copper(I) Cu+ cuprous
Common anions
hydride H−
fluoride F−
chloride Cl−
bromide Br−
iodide I−
oxide O2−
sulfide S2−
nitride N3−
phosphide P3−
