Iron is an element, therefore you can have a single atom of iron if you wish (on the Periodic Table of Elements the majority of the elements are single atoms). This excludes diatomic particles such as oxygen, or O2.
Great, now I can't get subscript off.
Anyway, you may be talking about iron; like a lump of iron. If this is the case, it is a METAL. It is made of many, many tiny iron atoms, which connect into molecules. But if you are wanting to go as far as possible into the iron to find its source, you're looking for atoms.
No, xenon is not a molecule. It is a chemical element, identified by the symbol Xe and atomic number 54. Xenon is a noble gas that exists as individual atoms rather than bonded together in a molecule.
Argon is a monatomic molecule because it exists as individual atoms (Ar) in its stable form, with no need to bond with other atoms. It is a noble gas with a full valence shell, making it energetically favorable to exist as a single, unreactive atom.
One molecule of iron oxide (Fe2O3) contains two iron atoms per molecule. So, for every molecule of iron oxide, there are two iron atoms, which means one iron oxide molecule contains two iron atoms.
Kr is not a monatomic element. Kr is the chemical symbol for Krypton, which is a noble gas and exists naturally as a diatomic molecule (Kr2) rather than as individual atoms.
A monatomic molecule is made up of only one kind of atom (mono means one and atomic is lbasically the word atom). Argon is monatomic because it has a full outer shell of electrons and so generally doesn't form chemical bonds, this also makes it a noble gas.
monatomic molecule
Barium is monatomic so 56.
No, xenon is not a molecule. It is a chemical element, identified by the symbol Xe and atomic number 54. Xenon is a noble gas that exists as individual atoms rather than bonded together in a molecule.
A monatomic molecule contains only one atom. It is a single atom that is chemically stable. Examples include noble gases like helium and neon.
Argon is a monatomic molecule because it exists as individual atoms (Ar) in its stable form, with no need to bond with other atoms. It is a noble gas with a full valence shell, making it energetically favorable to exist as a single, unreactive atom.
One molecule of iron oxide (Fe2O3) contains two iron atoms per molecule. So, for every molecule of iron oxide, there are two iron atoms, which means one iron oxide molecule contains two iron atoms.
The molecule of nitrogen contain two atoms, is diatomic.
Neon is a monatomic gas, it dissovles slightly in water but causes no change to the pH as it is completely inert.
Kr is not a monatomic element. Kr is the chemical symbol for Krypton, which is a noble gas and exists naturally as a diatomic molecule (Kr2) rather than as individual atoms.
A monatomic molecule is made up of only one kind of atom (mono means one and atomic is lbasically the word atom). Argon is monatomic because it has a full outer shell of electrons and so generally doesn't form chemical bonds, this also makes it a noble gas.
One molecule of iron oxide (Fe₂O₃) contains two iron atoms.
Because it is a metal, iron does not form molecules. The chemical symbol of the element iron is Fe. This also serves as its chemical formula since it is monatomic.
