1oxide

1oxide is a term used in the field of chemistry to refer to the simplest oxide of an element, which typically contains one oxygen atom per molecule. The term is often used in the context of transition metals and their compounds. For example, iron(II) oxide, also known as ferrous oxide, is a 1oxide of iron, as it contains one oxygen atom per iron atom. Similarly, cobalt(II) oxide, or cobaltous oxide, is a 1oxide of cobalt. These oxides are often used in various applications, such as pigments, catalysts, and magnetic materials. The term 1oxide is also used in the context of main group elements, such as nitrogen monoxide (NO) and phosphorus monoxide (PO). However, it is important to note that the term 1oxide is not universally accepted, and some chemists prefer to use the term "monoxide" to describe these compounds.
