The simplest way to figure this out is as following: the atomic number of sodium is 11, which gives you the number of protons. The number of electrons = the number of protons. The number of neutrons is the atomic weight (22.98 in this case) rounded minus the number of protons. Therefore sodium has 11 protons, 11 electrons, and 12 neutrons. Hope this helps! :)
sodium's atomic number is 11 and since protons and electrons are the same number as the atomic number, there are 11 protons and 11 electrons, to get the neutrons you take the isotope of sodium you are given, in this case 23 and subtact the number of protons, so 23-11=12. Therefore there are 12 electrons.
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
10 neutrons(uncharged) 10 neutrons(uncharged)
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.
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
The atomic number is determined by the number of Protons. So in this case it would be 11 (Sodium). The mass number is the total of protons and neutrons, so in this case 23. So this isotope of sodium would be 23Na.
Sodium's atomic number is always 11 and is always the same as its protons.

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.
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.
It has 11 protons, so its atomic no. is 11. It is Sodium.
Atomic number: 11 Mass number: 23 (11 protons + 12 neutrons) Atomic mass (aka atomic weight): 22.98976928 Element: Sodium (sodium-23 is the only stable sodium isotope)
The atomic number of sodium is 11 so it has 11 protons. For Na-23 there are 12 neutrons (23 - 11 = 12)
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.
