'Na' is the atomic notation of sodium. Hope this helps :)
It is usually of the form 23Na where the 23 appears as a superscript.
23
11Na
Example for the isotope sodium-23: 2311Na
For example Na-23 or 2311Na.
Sodium chloride is a chemical compound not an isotope. But:- natural sodium contain the rare radioactive isotope 22Na and the stable isotope 23Na- natural chlorine contain the rare radioactive isotope 36Cl and the stable isotopes 35Cl and 37Cl
40K
For example a thorium isotope is Th-231 or 23190 Th.
The chemical notation is 19F.
1. Sodium has 20 isotopes and 2 isomers. 2. Only the isotope 23Na is stable. 3. The stable isotope 23Na and the radioactive isotopes 22Na and 24Na (these isotopes exist in traces) are natural isotopes.

Sodium chloride is a compound, not an isotope.
Sodium chloride is a chemical compound not an isotope. But:- natural sodium contain the rare radioactive isotope 22Na and the stable isotope 23Na- natural chlorine contain the rare radioactive isotope 36Cl and the stable isotopes 35Cl and 37Cl
Na -23 is the most abundant isotope, because the atomic massfor Na on the periodical table of elements is 22.99 and 22.99 isclosest to 23.
The number of protons in an atom determines what that atom is called. Therefore, sodium, or Na, always has 11 protons. The particular isotope of sodium that has 12 neutrons is called 23Na, and is the only stable isotope of sodium.
40K
Sodium has 11 electrons and protons; the number of neutrons is specific for each isotope. Number of neutrons in a sodium isotope = Mass number - 11
Sodium-23 and Sodium-22 are two common isotopes of sodium. Na-23 is the only stable isotope of Sodium. Na-22 is one of the two isomers (the other of which is Na-24). -V
For example a thorium isotope is Th-231 or 23190 Th.
