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.
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
An atom of Sodium weighs the same as 23 protons.
Sodium's atomic number is 11. Thus, neutral sodium has 11 protons and 11 electrons per atom. 23Na is sodium's only stable isotope, having 23 - 11 = 12 neutrons.
elecrons - 11 neutrons - 12 protons - 11
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
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.
12 neutrons are in the element sodium.
sodium-11 has 5 proton,5 electron and 6 neutron. hahaha...miss-a--danq2,cia2,stephai,trinang!
The isotope notation for sodium with 11 protons and 12 neutrons would be 23/11 Na.
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.
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).
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 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.
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.
