It could be either. For example, a molecule of O2 or Cl2 is an element, but one of CH4 or NO3 is a compound.
This is a compound, a molecule.
An atom for an ELEMENT and a molecule for a COMPOUND.
If it is an element, then the smallest particle that retains the characteristics of the element is an atom. If it is a diatomic element, then the smallest particle that retains the characteristics of the element is a molecule. If it is a molecular compound, then the smallest particle that retains the characteristics of the compound is a molecule. If it is an ionic compound, the smallest particle that retains characteristics of the compound is a formula unit.
H2 or hydrogen gas is neither a mixture nor a compound. It is an element because it is only made up of one element which is hydrogen.
Water is a pure compound -- all of it is one kind of molecule: H2O.
Nitrogen is an element that is usually found alone as the N2 molecule. It is not a compound.
This is a compound, a molecule.
Hydrogen is an element. Also a molecule.
NH3 is molecule of ammoia. It is not element
It's an element
No it is an element
Molecule
An element, atom, crystal, compound, and molecule are all forms of matter.
No, a compound is a molecule composed of MORE THAN ONE type of element.
O3 is a molecule / compound, not element
The simplest structured unit in a compound is a molecule.
Its an element and an atom.
