This is a compound, a molecule.
It could be either. For example, a molecule of O2 or Cl2 is an element, but one of CH4 or NO3 is a compound.
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.
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 could be either. For example, a molecule of O2 or Cl2 is an element, but one of CH4 or NO3 is a compound.
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.
