The chemical formula for cobalt(II) sulfide is CoS. It consists of one cobalt atom and one sulfur atom.
In one atom of cobalt ion, the number of neutrons can vary based on the isotope. The most common isotope of cobalt is cobalt-59, which has 33 neutrons.
In a cobalt atom, there are 27 electrons. This number is found by looking at the atomic number of cobalt on the periodic table, which is 27. Electrons are equal in number to the protons in a neutral atom.
The formula for 1 atom of cobalt reacting with 2 atoms of chlorine is CoCl2, known as cobalt(II) chloride. In this compound, cobalt has a +2 charge, and each chlorine atom has a -1 charge, resulting in the chemical formula CoCl2.
As the name tells you, it consists of atoms of cobalt and chlorine. More than one atom in that molecule.
