It is usually of the form 23Na where the 23 appears as a superscript.
The isotope notation for sodium with 11 protons and 12 neutrons would be 23/11 Na.
'Na' is the atomic notation of sodium. Hope this helps :)
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.
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, not an isotope.
Sodium (Na) has an atomic number of 11, which means it has 11 protons, regardless of its isotope. The notation "Na-3" suggests it is a hypothetical isotope of sodium with an atomic mass of 3, but this is not stable or commonly recognized. In any case, the number of protons in sodium remains 11.
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
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.
All atoms of sodium contain 11 protons, since 11 is the atomic number of sodium.
The chemical notation for the element sodium is Na.
