Sodium does have an atomic number of 11, and if the isotope's Atomic Mass is 23, the atom would have 11 protons (the atomic number) and 12 neutrons (the atomic mass minus the atomic number). The atom would have 11 electrons, and when ionized it would lose one and take on a charge of +1.
12 neutrons and 11 protons.
must be 12

Sodium (Na) has atomic number 11 and atomic mass of 22.99 g/mol
Mass number is the number of protons and neutrons in the nucleus of an atom. Atomic number on the periodic table is the number of protons in the nucleus of an atom. mass number - atomic number = number of neutrons The atomic number of sodium is 11. Specified mass number is 23. Therefore, 23-11 = 12 neutrons
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.
Subtract the atomic # from the atomic mass. Atomic number = number of Protons. Atomic mass = total nucleons (Protons + Neutrons).Atomic # = 11 and Atomic Mass = 23. So 23-11 = 12 Neutrons.
Just remember the atomic number is the amount of protons and electrons there is 11 in sodium, and 12 neutrons in sodium. To find neutrons you round the atomic mass if needed then subtract it from the number. So sodium's mass is 22.9 so you round it to 23 subtracted by the atomic number, which is 11 giving you 12. Hope that helps

Subtract the proton number or atomic number (11) from the nucleon number or the atomic mass (23) and you get the number of neutrons = '''12'''.

The atomic number is 4
Its atomic number is 11 and its mass is 22.99. This atom is a sodium atom.
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.
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
12 neutrons has nothing to do with atomic number. Atomic number is the number of protons. You might mean sodium. Sodium has an atomic number of 11, and an atomic mass that rounds to 23, so 23 -11 = 12 neutrons in some isotopes of sodium. but some atoms of magnesium atomic number 12 also have 12 neutrons with a mass number of 24, and probably some other element, but those are all I can think of now.
The atomic number is 11 and atomic mass is 23. The number of protons and electrons in sodium is 11 and the number of neutrons is 12
