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 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).
An atom of Vanadium (V) has 23 protons since it is the 23rd element on the periodic table. To find the number of neutrons, you subtract the atomic number (23) from the atomic mass of Vanadium, which is approximately 50.94. This gives you approximately 28 neutrons in an atom of Vanadium-50 (50V).
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.
there are 11.99 neutrons in an atom of sodium
This atom is sodium with an atomic number of 11 (number of protons) and an atomic mass of 23 (sum of protons and neutrons). It has one more electron than protons, giving it a net charge of +1.

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.

Vanadium has an atomic no. of 23 and mass number of 51. But it has 28 neutrons and 23 electrons
Protons and neutrons each have an atomic mass of 1 So, 38-15=23 Neutrons
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).

An atom of Sodium weighs the same as 23 protons.
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.
there are 11.99 neutrons in an atom of sodium
The mass number of an atom is the sum of its protons and neutrons. In this case, the mass number of the sodium atom with 11 protons and 12 neutrons would be 23.
This atom is sodium with an atomic number of 11 (number of protons) and an atomic mass of 23 (sum of protons and neutrons). It has one more electron than protons, giving it a net charge of +1.
