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.
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).
Sodium is element nr. 11, which means 11 protons, so 25 - 11 = 14. Note that there is no actual Sodium isotope with mass 25.
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.
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 atomic number is determined by the number of Protons. So in this case it would be 11 (Sodium). The mass number is the total of protons and neutrons, so in this case 23. So this isotope of sodium would be 23Na.
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
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.
elecrons - 11 neutrons - 12 protons - 11
sodium-11 has 5 proton,5 electron and 6 neutron. hahaha...miss-a--danq2,cia2,stephai,trinang!
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 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.
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).
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
12 neutrons are in the element sodium.
Sodium is element nr. 11, which means 11 protons, so 25 - 11 = 14. Note that there is no actual Sodium isotope with mass 25.
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.
A sodium isotope with a mass number of 25 would have 11 protons, as sodium typically has 11 protons in its nucleus. The mass number represents the total number of protons and neutrons in an atom, so subtracting the number of neutrons (in this case, 25 - 11) gives the number of protons.
