Sodium chloride is a compound made up of sodium and chlorine ions, not an isotope. Isotopes are variations of an element that have the same number of protons but different numbers of neutrons. Sodium and chlorine have isotopes, but sodium chloride is a fixed compound.
The hyphen notation of the most common isotope of technetium, technetium-98, is 98Tc.
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.

For example a thorium isotope is Th-231 or 23190 Th.
The isotope notation for sodium with 11 protons and 12 neutrons would be 23/11 Na.
The isotope notation for sodium with 11 protons and 12 neutrons would be Sodium-23, where the number 23 represents the sum of protons and neutrons in the nucleus.
It is usually of the form 23Na where the 23 appears as a superscript.
It is usually of the form 23Na where the 23 appears as a superscript.
Sodium chloride is a compound, not an isotope.
The symbol for a sodium isotope with 12 neutrons would be "Na-23". This notation indicates the element symbol "Na" for sodium and the total number of protons and neutrons in the nucleus (12 neutrons + 11 protons = atomic mass number 23).
Sodium chloride is a compound made up of sodium and chlorine ions, not an isotope. Isotopes are variations of an element that have the same number of protons but different numbers of neutrons. Sodium and chlorine have isotopes, but sodium chloride is a fixed compound.
The appropriate symbol for an isotope of potassium-39 corresponding to the isotope notation A Z X is ^39_K19.
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.
An isotope of sodium with a mass number of 20 will have 11 protons because sodium always has 11 protons, regardless of the isotope.
The chemical notation for the element sodium is Na.
The hyphen notation of the most common isotope of technetium, technetium-98, is 98Tc.
