It doesn't actually exist. Only been proposed.
The atomic radius of cobalt is about 135 pm (±5 pm).

Cobalt is a chemical element and has atoms.
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.
Cobalt is a chemical element with the symbol Co and atomic number 27. It consists of only one type of atom, which is the cobalt atom itself. While cobalt can exist in different isotopes (such as cobalt-59 and cobalt-60), they are still variations of the same element and not different types of atoms. Thus, cobalt is characterized by a single type of atom in its elemental form.
The atomic radius of cobalt is about 135 pm (±5 pm).

Every cobalt atom has 27 electrons regardless its isotope.
Cobalt is an element, there is no oxygen.
Cobalt is a chemical element and has atoms.
The chemical formula for cobalt(II) sulfide is CoS. It consists of one cobalt atom and one sulfur atom.
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.
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.
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.
