Na is Sodium, and since everything is made of molecules, I would assecertain that NA is therefore a molecule.

Na+ is not a molecule; it is an ion, specifically a sodium ion.
No.
Na = +1 Na2 = Na(2) = +2
Two atoms in the formula unit (not molecule): Na and Cl.
The DNA molecule comes together and make protein. This is formed in our bodies.
yes they exsist as monoatomic molecule in vapour state
H2O. Notice the presence of two elements, H and O. Each of the other three is an element.
The electrostatic force of attraction between the positively charged sodium ion (Na+) and the negatively charged chloride ion (Cl-) holds the Na-Cl molecule together in an ionic bond.

A sodium (Na) atom is neither an ion nor a molecule. It is a single, neutral atom with 11 protons in its nucleus and 11 electrons orbiting around it. An ion is when an atom gains or loses electrons to become charged, and a molecule is a combination of atoms bonded together.
The oxygen end of the water molecule is attracted to the Na+ ion. This attraction occurs due to the partial negative charge on the oxygen atom of the water molecule and the positive charge on the sodium ion.
Sodium is a chemical element not a molecule; the symbol is Na.
