there are 11.99 neutrons in an atom of sodium
The answer cannot be determined with atomic weight. You are asking for the number of neutrons in a particular isotope of sodium. You need mass number for the isotope you are interested in, which is probably 23.Assuming you mean atomic number of 11 and a mass numberof 23, there would be 12 neutrons in each atom of this isotope.
It depends on which isotope you are talking about. The stable form of sodium is 23Na, which has 11 protons and 12 neutrons. Isotopes of sodium range from 18Na, with 7 neutrons, to 37Na, with 26 neutrons.
Atoms of the same element usually have the same number of protons but differ slightly in the number of neutrons. The number of neutrons are usually about the number of protons so it can be estimated as so. For example, there are two relatively common isotopes of sodium: sodium 22 and sodium 23, where the number is the total number of protons and neutrons. Sodium 22 has 11 neutrons and sodium 23 has 12 neutrons but the sodium atom has 11 protons. For further information, look up isotopes.
The number of neutrons in the nucleus of an atom is always the difference between the mass number of the atom and the atomic number of the atom. Therefore, in this instance, there are (155 - 63) or 92 neutrons in the atom.

there are 11.99 neutrons in an atom of sodium
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
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.

Electrons~ 11 Neutrons~11 12Protons~11Youre welcome(;___________________________ (Improved answer) No, It has 11 electrons, 11 protons and 12 neutrons.
sodium has more protons and neutrons. electrons have practically no mass, valence electrons are just outer orbital electrons. sodium has 11 protons, 11 electrons, and 12 neutrons. Mass is 23. neon has 10 protons, 10 electrons, and 10 neutrons. Mass is just 20. The neon atom has 10 protons and 10 neutrons for a mass number of 20. The sodium atom has 11 protons and 12 neutrons for a mass number of 23. The number of valence electrons has no bearing on mass number or atomic weight.

The number of neutrons depends on the atom. In general, mass number = atomic number + number of neutrons.
A neutral sodium atom consists of 11 protons, 11 electrons, and usually 12 neutrons.
