Is gold monatomic or diatomic?
Some sources cite the different color of the gold from its usual yellow color as evidence of it being monatomic. Any chemist (or alchemist, for that matter) knows gold is a transition metal that forms colored complexes and also assumes different colors as a pure metal as a thin film.
Why are they called polyatomic ions?
The prefix poly- means many, so a polyatomic ion is an ion that contains more than one atom. This differentiates polyatomic ions from monatomic ions, which contain only one atom.
What is a polyatomic ion easy definition?
Polyatomic ions are ions which consist of more than one atom. For example, nitrate ion, NO3-, contains one nitrogen atom and three oxygen atoms. The atoms in a polyatomic ion are usually covalently bonded to one another, and therefore stay together as a single, charged unit.
Is water polyatomic?
definition. …than two atoms are termed polyatomic molecules, e.g., carbon dioxide (CO2) and water (H2O).
What is a polyatomic element?
A polyatomic element is a chemical element that naturally exists as a compound molecule containing more than two atoms of the same element joined together by covalent bonds. There are only three polyatomic elements found on the periodic table: selenium, phosphorous and sulfur.
Is Iron Monatomic?
A monatomic ion is an ion consisting of exactly one atom. If an ion contains more than one atom, even if these are of the same element, it is called a polyatomic ion….Monatomic ion.

Is Phosphorus a polyatomic ion?
Phosphorus is listed as a single element in the periodic table; however, I see that it is also a polyatomic molecule as P4. For example the word equation is P+Cl⟶PCl5.
Why is phosphorus polyatomic?
Phosphorus can form a P4 white phosphorus tetrahedron because it can form three bonds, while sulfur can only form two bonds. Therefore sulfur forms rings and chains only. The most stable allotrope of phosphorus, red phosphorus, is a cross-linked, polymeric chain of atoms.
