This is carbon monoxide. It is made up of 2 harmless elements, one atom of carbon and one atom of oxide. This results in carbon monoxide.
Carbon monoxide is a colourless, odorless and tastless gas that is slightly lighter than air. It is toxic to humans and animals in large amounts.
This compound in bonded through covalent bonding as both carbon and oxide are non-metals.

Carbon: Carbon is a naturally abundant nonmetallic element which forms the basis of most living organisms. Carbon is the fourth most abundant element in the universe, and it plays a crucial role in the health and stability of the planet through the carbon cycle.
Oxide:An oxide is an anion of oxygen in the oxidation state of -2 or a chemical compound formally containing an oxygen in this state. Most of the Earth's crust consists of oxides. Oxides result when elements are oxidized by oxygen in air.
Formation: In carbon, it is four electrons away from becoming a noble gas and oxide is two short from becoming a noble gas. Hence a coordinate covalent bond is formed and carbon monoxide is formed.
