Aluminum is an element, composed of molecules, is on the periodic chart, does exist by itself AND can be combined to form compounds.
in theory, that would describe Xenon octochloride However, this molecule is not reported to exist
Neon - it is a noble gas and does not even combine with itself
The chemical compound C3H3 has two element in it: Carbon and Hydrogen. In one molecule of this compound there are 6 atoms: 3 Carbon atoms and 3 Hydrogen atoms. Both elements in this compound, Carbon and Hydrogen are classed as other nonmetals. However this compound does not exist 'in real chemical life', it's a fantasy formula.
The molecule of methane is more stable, carbon is tetravalent.
Potassium chloride is a ionic lattice which is made out of potassium ions and chloride ions. Therefore, separate 'molecules of this compound do not exist. The empirical formula itself is KCl which is used also as the chemical formula for the compound.
Yes, elements and compounds can exist separately.
molecule
You can control the number of water molecules that exist in a hydration compound by regulating the number of hydrogen and hydroxyl ions.
A molecule Ni3 doesn't exist; you think probable to a compound of Ni(III).
in theory, that would describe Xenon octochloride However, this molecule is not reported to exist
There is no such molecule as C6H2O, it cannot exist.
The compound Cl3 does not exist (did you mean chlorate?). Triatomic hydrogen H3 does exist however but is an unstable molecule.
The compound HeNe exist but it is difficult to obtain this molecule and is very unstable.
This compound doesn't exist by itself. When it is in a larger compound it is called oxide because it is an anion of oxygen.
A molecule is the combination of two or more atoms which may exist free in nature. Does this mean that one atom of heliom is NOT a molecule? yes it is not a molecule it is an atom that exists free as a molecule so the term monoatomic molecule is used for noble gase but not only molecule.
MgCI2 does not exist. The formula is MgCl2 with a lowercase L. This compound is ionic.
a molecule can be a compound if it is made of more than one type of atom.
