Isotope 24Na (or Na-24) has 11 protons and 13 neutrons, its mass number is 24
Isotope 23Na is the stable form of Na with 11 protons, 12 neutrons and with mass number 23.
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.
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.
An atom of Sodium weighs the same as 23 protons.
11 protons and 12 neutrons for Na-23, the (only) naturally occurring isotope. 11 protons and 11 neutrons for Na-22, artificial isotope, 2.6 yr. halflife time 11 protons and 13 neutrons for Na-24, artificial isotope, 14.8 hr. halflife time
No, the Neutrons vary with the element, in the same group as well, it depends on the isotope, like lithium for example, the most commonly occurring isotope has 4 neutrons, whereas sodium has 12
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
12 neutrons are in the element sodium.

Sodium atoms always have 11 protons. Since the mass number is the sum of protons and neutrons, one can find the number of neutrons by subtracting the number of protons from this number. Thus, sodium 25 has 14 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 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.
Sodium-23 the only isotope occuring in nature has 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.
Na-23
An atom of Sodium weighs the same as 23 protons.
Sodium, Na, is the element that has eleven protons.
Sodium is element nr. 11, which means 11 protons, so 25 - 11 = 14. Note that there is no actual Sodium isotope with mass 25.
