That depends on which isotope of sodium you are talking about. Sodium always has 11 protons. The Atomic Mass of sodium is about 23, meaning there are, on average, 12 neutrons, so the average neutron to proton ratio for sodium is 12:11.
n:p=12:11
8=====D that answer is wrong someone fix it
(I already did this in the 2nd discussion, in direct communication at the Q's messageboard,
and below this line:)
Sodium has 11 protons (= atom number: 11)
Mass number is 23 (isotope:Na-23)
Number of neutrons = Mass number (23) MINUS number of Protons (11) =(23-11)=12
I don't see what is wrong to that answer of mine.
11
Answer:
11 if you are looking 4 Na (pure sodium) but are you looking for NaCl (table salt)?
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
Neutron/Proton Ratio
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 does not have naturally occurring radioactive isotopes - as it has only 1 naturally occurring isotope, which has 11 protons and 12 neutrons, and is not radioactive. However, the 18 other known types of sodium isotopes are all radioactive, and sodium-22 (the most stable radioactive sodium isotope) has a half life of 2.6 years.
'Na' is the atomic notation of sodium. Hope this helps :)

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.
In sodium chloride, the ratio is 1/1.
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
The atomic ratio in this salt is 1:1. The mass ratio is 22.999:35.457 of sodium to chlorine, the ratio of the atomic weights of sodium and chlorine.
Neutron/Proton Ratio
no symbol
The atomic ratio between sodium and chlorine in sodium chloride is 1:1, as indicated by its formula NaCl. If the mass ratio is wanted, it is that of the atomic weights of the two elements.
Sodium-23 the only isotope occuring in nature has 12 neutrons
