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
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.
The sodium atom has 11 protons 11 electrons and 12 neutrons.
12
Sodium's atomic number is always 11 and is always the same as its protons.
12 neutrons are in the element sodium.
Sodium has 12 neutrons. Chloride ion has 18 neutrons. In a formula unit, NaCl has 30 neutrons.
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
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
It would become an isotope. Isotopes have different numbers of neutrons.
In Sodium there are 1 amu of protons and neutrons. There are also 11 protons and 11 electrons. There are 11 neutrons in Sodium 22.
Sodium has 11 protons, 11 electrons and 12 neutrons.
What they have in common is that they all have 11 protons in the nucleus.How they differ is that they have different numbers of neutrons in the nucleus.
There are 12 neutrons in sodium
