Carbon dioxide is a linear structure with two double bonds between carbon and oxygen. It is a small molecule and non-polar with only weak bonds between the molecules. Hence it is a gas. read more

Carbon dioxide consists of molecules in which a single carbon atom is double-bonded to two oxygen atoms. As CO2 is a relatively small, nonpolar molecule it is a gas. Silicon itself is a metalloid with a relatively large atomic radius while oxygen has a much smaller atomic radius. read more

Carbon dioxide is a compound of two molecules - Carbon and Oxygen. CO2 can become a solid at approximately -70 F or -56C at which point it is referred to as dry ice in the vernacular. Silicone Carbide is a compound of solids, Silicone and Carbon. read more
