Na-23
The isotope notation for sodium with 11 protons and 12 neutrons would be 23/11 Na.
elecrons - 11 neutrons - 12 protons - 11
Sodium, Na, is the element that has eleven protons.
12 neutrons are in the element 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.
The isotope notation for sodium with 11 protons and 12 neutrons would be 23/11 Na.
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).
elecrons - 11 neutrons - 12 protons - 11
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
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, Na, is the element that has eleven protons.
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.
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 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.
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.
