What element is CO NO3?

In chemistry, CO NO3 represents a compound of carbon monoxide and nitrogen that contains the elements carbon (C), oxygen (O) and nitrogen (N). An element contains only one type of atom, whereas a compound contains multiple atoms of different elements bonded together, according to New York University

Carbon monoxide and nitrate do not typically react, although nitrate can be used to oxidize carbon monoxide. Oxidation is the process by which a compound either loses or gains atoms of oxygen. The symbol for the different elements can be found on the periodic table of elements, along with some of their specific characteristics. For example, carbon monoxide is a colorless gas, and nitrate is an ion with a charge of -1.
