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.
Electrons~ 11 Neutrons~11 12Protons~11Youre welcome(;___________________________ (Improved answer) No, It has 11 electrons, 11 protons and 12 neutrons.
Um. Atom? Element? If it has an equal number of protons and electrons, it has a neutral charge, so is not an ion. If it is not bonded to anything, it is not a molecule. You could call it an isotope of Boron, however this term is usually only used for less common isotopes, meaning atoms with different numbers of neutrons, and the atom with 6 neutrons is the most common isotope of Boron. Is there any more information in the question, or does anything happen to this atom?
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 is element nr. 11, which means 11 protons, so 25 - 11 = 14. Note that there is no actual Sodium isotope with mass 25.
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
Answer: 28 protons 28 electrons; the number of neutrons depends on each isotope of Na and Cl considered.
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.
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 mass of the isotope 7Be is 7,01692983(11) u. The isotope 7Be has 4 protons, 3 neutrons and 4 electrons (not 6).
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
There would be 6 protons and 5 neutrons. Such isotope does not exist though.
The atomic number is 8. It is a non-existent isotope of oxygen.
sodium's atomic number is 11 and since protons and electrons are the same number as the atomic number, there are 11 protons and 11 electrons, to get the neutrons you take the isotope of sodium you are given, in this case 23 and subtact the number of protons, so 23-11=12. Therefore there are 12 electrons.
The element with 8 protons and 8 electrons is oxygen (O). The presence of 11 neutrons indicates a specific isotope of oxygen, oxygen-19.
The isotope 25Na has 11 protons and electrons and 14 neutrons.
This is not an atom. This is an ion. This is Na+ ion.
