There are four atoms - One Carbon atom and Three Oxygen atoms.
CO3 - The elements present in this are one carbon atom and three oxygen atoms, CO3 is a base, the name of it is carbonate, K2CO3 = potasium carbonate
CO3 is a carbonate ion with a 2- charge, formed by the covalent bonding of one carbon atom and three oxygen atoms.
The formula unit contain 1 calcium atom, 1 magnesium atom, 2 carbon atoms and 6 oxygen atoms.
The symbol "CO3" stands for the chemical compound Carbon Trioxide. C stands for Carbon O stands for oxygen 3 represents how much oxygen there is (if the 3 was in between the "C" and "O" then it would represent the amount of carbon)
The oxidation number of C in CO3^2- is +4. Each oxygen atom has an oxidation number of -2, and since the overall charge of the carbonate ion is 2-, the carbon atom must have an oxidation number of +4 to balance the charge.
The chemical formula of a carbonate ion is CO3^2-. It consists of one carbon atom covalently bonded to three oxygen atoms.
The oxidation number of CO3 in NiCO3 is -2. In this compound, each oxygen atom has an oxidation number of -2, and since there are three oxygen atoms in CO3, the overall charge for the carbonate ion is -2. Therefore, the oxidation number of CO3 is -2 in NiCO3.
The oxidation number of carbonate ion (CO3) is -2. Each oxygen atom has an oxidation number of -2, and the sum of the oxidation numbers in the ion must equal the charge of the ion, which is -2.
CO3 is most commonly known as carbon trioxide. It is the combination of carbon dioxide and atomic oxygen. It is a reaction when the two are combined, and is considered to be an unstable element.
trigonal planar, as there are 3 o atoms around c atom and no lone pairs is present.
The molecular geometry of the compound CO32- is trigonal planar. It has a single atom of carbon bound to three atoms of oxygen.
Magnesium carbonate (MgCO3) is composed of one magnesium (Mg) atom and one carbonate (CO3) ion.
