Cobalt is a chemical element and has atoms.
As the name tells you, it consists of atoms of cobalt and chlorine. More than one atom in that molecule.
There is no reason at all why cobalt cannot be combined with more cobalt. It can. Cobalt is a metal. It can be recovered from ore and refined, then melted down with other cobalt pieces to form one large mass of the metal.
Every cobalt atom has 27 electrons regardless its isotope.
Cobalt is an element, there is no oxygen.
CoCl2 is a formula unit, as it represents the chemical formula for cobalt (II) chloride, which is an ionic compound consisting of cobalt ions (Co2+) and chloride ions (Cl-). It is not a diatomic molecule, which would consist of two atoms of the same element bonded together.
Is both because is a compound and a molecule.
The chemical formula for cobalt(II) sulfide is CoS. It consists of one cobalt atom and one sulfur atom.
Is Ne a atom or molecule
no an atom is a part of a molecule.
A carbohydrate is a molecule, not an atom.
