A monatomic ion is an ion consisting of a single atom. If an ion contains more than one atom, even if these atoms are of the same element, it is called a polyatomic ion.For example, calcium carbonate consists of the monatomic ion Ca 2+ and the polyatomic ion CO 3 2â .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.or example, calcium carbonate consists of the monatomic ion Ca 2+ and the polyatomic ion CO 3 2â . A type I binary ionic compound contains a metal (cation) that forms only one type of ion.

Active Template Library (ATL) Tutorial. ATL is designed to simplify the process of creating efficient, flexible, lightweight controls. This tutorial leads you through the creation of an ActiveX control, demonstrating many ATL and COM fundamentals. By following this tutorial, you will learn how to add a control to an ATL project that draws a circle and a filled polygon. You will then add a property to indicate how many sides the polygon will have and create drawing code for updating the control when the property changes.
