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.

How many neutrons are in an atom of sodium with mass number 23?

Why does an atom of sodium have more mass than an atom of neon?
Sodium is atomic number 11, while neon is atomic number 10. We would already expect sodium to be heavier, but the most common stable isotope of sodium has 12 neutrons, and the most common stable isotope of neon has only 10. Since the atomic weight can be approximated by the sum of neutrons and protons (and the number of protons is the atomic number), we can guess that sodium's atomic mass is 23 and neon's is 20.
An element has a atomic number of 11 and an atomic weight of 23 how many neutrons does each atom contain?
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.
If an atom has 11 protons 12 neutrons and 11 electrons what is the identify of the element and it's mass number?
It is a radioactive scandium isotope - 43Sc with 21 electrons and protons, and 22 neutrons.

How does an atom of sodium has a larger mass than a atom of neon. how is this possible when neon has so many more valence electrons?
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.

What atom has an atomic number of 23 12 neutrons and how many electrons?
Vanadium has an atomic no. of 23 and mass number of 51. But it has 28 neutrons and 23 electrons
If the atomic mass of an atom is 38 and the atom contains 15 protons how many neutrons does the atom contain?
Protons and neutrons each have an atomic mass of 1 So, 38-15=23 Neutrons
If a particular isotope of sodium has a mass of 23 how many neutrons does it have?
An atom of Sodium weighs the same as 23 protons.
The nucleus of an atom k-42 contains?
19 Protons and 23 Neutrons
Why does an atom of sodium have more mass than an atom of neon?

How many neutrons and protons does neutral atom of sodium with an atomic mass number of 23 have?
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.
How many neutrons does sulfur 23 have?
Sulfur is a non metal element. There are 16 electrons in a single atom.
What is the mass of an atom that has 10 protons 13 neutrons 10 electrons?
The mass number of this atom is 23, the sum of the number of protons and neutrons.
