A chemical compound always consists of two or more elements combined together, and therefore molecules of at least two atoms. A substance which was only one element would simply be a sample of the element. There are some monoatomic
elements, the noble gases, helium and group 18 neon argon etc.
Because it has to have more than one atom to be a compound.
Monatomic means having only one atom. A compound is made up of at least two different elements, and therefore cannot have just one atom.
nitrate
Ammonium, NH4+
Monatomic means having 1 atom.
Yes. All the noble gasses are monatomic.
These are the elements that are NATURALLY monatomic: Helium Neon Argon Krypton Xenon Radon
Because it has to have more than one atom to be a compound.
Sulfur hexafluoride is not a monatomic ion but in fact a molecular compound.
monatomic
Polyatomic ionic.
Nitrate

Monatomic means having 1 atom.
'Monatomic' means having or consisting of single atoms.
Yes. All the noble gasses are monatomic.
Sodium sulfate is an ionic compound, composed of monatomic and monovalent sodium cations and polyatomic and divalent sulfate anions. The anions are internally covalently bonded, but are not compounds because they are not electrically neutral.
