Br is a molecule.
Bromine is an element and has the symbol Br.
A formula unit of NaBr contains 2 atoms: 1 sodium and 1 bromine.
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.
Xenon is an element, not a molecule or a formula unit. It is a noble gas that exists as single atoms in its elemental form.
Formula: BrCl6
a molecule of bromine
The formula unit is the representation of a molecule.
Bromine is diatomic, which means it is naturally found as Br2
The chemical formula of magnesium bromide is MgBr2; 2 is the number of bromine atoms in the molecule.
Magnesium bromide IS a molecule, or more correctly, it is a formula unit. So, magnesium bromide doesn't HAVE any molecules. One formula unit of magnesium bromide has THREE ATOMS, and they are 1 magnesium atom and 2 bromine atoms (MgBr2).
Another name for a molecule is a formula unit.
No. It is a molecule. The term formula unit is generally reserved for ionic compounds.
SiF4 is a molecule
Bromine is an element and has the symbol Br.
Bromine's formula is Br2 (the two is a subscript), no matter what state of matter. This is because it is a diatomic element. All diatomic elements don't like being "lonely", so it will pair up with another one of itself. Bromine (Br), Iodine (I), Nitrogen(N), Chlorine (Cl), Hydrogen (H), Oxygen(O), and Fluorine(F) are the diatomic elements. (A good way to remember those is BrINClHOF- try saying it.)
For sodium chloride the term formula unit is more adequate than molecule; and the formula unit has two atoms.
The chemical formula P2O5 represents a formula unit. This is because P2O5 is an ionic compound, consisting of a combination of phosphorus and oxygen ions in a fixed ratio.
