11, 12 or 13 (12 is stable).
Every sodium atom has 11 protons, the atomic number of sodium. The isotope with mass number 23 has (23 - 11) or 12 neutrons, because the mass number of an isotope is defined as the sum of the numbers of protons and neutrons in the isotope.
12 neutrons
Because atoms can be isotopes or ions, protons are the only stable identifier for an element (Sodium can have more or less than normal number of electrons or neutrons and still be sodium). Sodium has 11 protons.
Every sodium atom has 11 protons, the atomic number of sodium. The isotope with mass number 23 has (23 - 11) or 12 neutrons, because the mass number of an isotope is defined as the sum of the numbers of protons and neutrons in the isotope.
There are 12 neutrons in a Sodium atom. To determine the number of neutrons in a specific element's atom, find the number of protons (its atomic number, which in this case is 11) and subtract it from the mass number (the number below the symbol in a periodic table rounded which in this case is 23).Sodium23 has 12 neutrons.there are 12 neutrons in a sodium atom
Sodium has 11 protons and usually 12 neutrons in its nucleus, giving it an atomic mass of 23 units. The nucleus of sodium can also have isotopes with different numbers of neutrons, such as sodium-22 and sodium-24.
Sodium's atomic number is always 11 and is always the same as its protons.
yes BECAUSE THEY SHOW THAT IN THE PERIODIC TABle SEVERAL THINGS OCCUR THEREFORE I AGREE WITH THIS STATEMENT
The atomic number is 11 and atomic mass is 23. The number of protons and electrons in sodium is 11 and the number of neutrons is 12
Sodium typically has 12 neutrons.
12 neutrons are in the element sodium.
Every sodium atom has 11 protons, the atomic number of sodium. The isotope with mass number 23 has (23 - 11) or 12 neutrons, because the mass number of an isotope is defined as the sum of the numbers of protons and neutrons in the isotope.
Sodium has 12 neutrons. Chloride ion has 18 neutrons. In a formula unit, NaCl has 30 neutrons.
12 neutrons
For sure the sodium atomic nucleus contains 11 protons. The natural isotope of sodium(23) also contains 12 neutrons, but other isotopes are possible with less or more of them in the nucleus. Still 11 protons, always!
The proton number of Sodium is 11. The mass number is just under 23 (22.989...). This is because of the different isotopes of sodium and there scarcity.
elecrons - 11 neutrons - 12 protons - 11
