there are 11.99 neutrons in an atom of sodium
An atom of sodium with mass number 23 has 12 neutrons. This can be calculated by subtracting the atomic number (which is 11 for sodium) from the mass number (which is 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
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
An atom's number of neutrons can be calculated by subtracting the atomic number (which represents the number of protons) from the atomic mass number. For sodium (Na) with an atomic number of 11, the atomic mass number is approximately 22. By subtracting, we find that there are approximately 11 neutrons in a sodium atom with an atomic mass of 22.

A sodium atom typically has 12 neutrons. This is because the atomic number of sodium is 11, which represents the number of protons in the nucleus. The total mass number of sodium is around 23, so subtracting the atomic number from the mass number gives us the number of 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.
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.
An element with an atomic number of 11 has 11 protons in its nucleus. To find the number of neutrons, subtract the atomic number from the atomic weight (23 - 11 = 12), so each atom contains 12 neutrons.
