Any pure, monatomic element cannot be a molecule.
Here are a few non-examples of a molecule;

My personal favorite is Oxygen, diatomic (two atoms per molecule) at Standard Temperature and Pressure, triatomic (three atoms per molecule) when in upper atmosphere where it is exposed to radiation or lower atmosphere when large electric current is passed through it (electric sparks and lightning). Nitrogen and Hydrogen are close seconds, both diatomic in gas state. Many pure solids can be considered a molecule, though some teachers make a distinction between crystaline bonds and molecular bonds.
O2 is an oxygen molecule that is not a compound. Compounds are two different chemicals combining and forming a new substance like H2O.
One example is a hydrogen molecule, H2.
N2 is an example.
A non example of a molecule is carbon to co2
Sulfur
A compound is two or more different elements bonded together. A molecule is two atoms bonded together. C02 is a compound and a molecule. H2 is only a molecule, as there is only hydrogen in the formula.
When the bond dipoles cancel one another out. Fro example in CCl4 the bonds are polar but the molecule is non-polar (no dipole moment) as the bond dipoles all cancel out.
a non polar molecule
No, not necessarily. It all depends on the symmetry of the molecule. Take a look at Carbon dioxide. It has a linear shape like this : O=C=O Although the bonds are obviously polar, the molecule is symmetrical. This makes the polarities of the bonds "cancel" each other, so to speak. So overall, this molecule is non-polar. If you take a look at Hydrogen chloride, on the other hand, it has a shape like this: H-Cl The molecule is assymmetrical, so this is a polar molecule.
no. it is a non-polar covalent molecule
Atom, Molecule, Compound, Element, DNA, etc..
A compound is two or more different elements bonded together. A molecule is two atoms bonded together. C02 is a compound and a molecule. H2 is only a molecule, as there is only hydrogen in the formula.
Every molecule has a polarity. They can either be non-polar (same on both sides) or polar (different on both sides). For example the molecule CO2 is a non-polar molecule. H20 (water) is a polar molecule (due to Valence Shell Electron Pair Repulsion theory (VSEPR)).
yes it is a non polar molecule
A non-polar molecule is a molecule that is symmetrical in the sense that the atoms on the outside pull equally on the central atom, thus not causing any differences in electronegativity.
When the bond dipoles cancel one another out. Fro example in CCl4 the bonds are polar but the molecule is non-polar (no dipole moment) as the bond dipoles all cancel out.
Water molecule is an important and good example of polar covalent molecule

a non polar molecule
The polarity of the molecule will depend on the electronegativities of the 2 atoms involved. For example, a molecule of F2 where F binds to F will be non polar as there is no difference in electrnegativities. However, a molecule of HF will be polar because F is more electronegative than is H.

O2 is non polar molecule .
