The atomic number of an element gives its number of protons per atom. Sodium's atomic number is 11. Thus, sodium has 11 protons per atom.

how are what is somali
The sodium atom has 11 protons 11 electrons and 12 neutrons.
The protons are in the nucleus. It's the electrons that are in the "shells" around the nucleus. There's just one electron in the third shell of the sodium atom.
The atomic number is the number of protons in an atom of an element. For example, Sodium's atomic number is 11. This tells us that an atom of sodium has 11 protons in its nucleus. The interesting thing here is that every atom of sodium contains 11 protons. If an atom doesn't have 11 protons, it can't be an atom of sodium. Adding or removing protons from the nucleus of an atom creates a different element. For example, removing one proton from an atom of sodium creates an atom of neon.
A NaCl (sodium chloride) atom contains one sodium (Na) atom and one chlorine (Cl) atom. Sodium has 11 protons and chlorine has 17 protons. They bond together through an ionic bond to form the compound sodium chloride.
11 electrons in a neutrally charged atom of sodium . It is the same number as the number of protons and the Atomic Number. However, the sodium ion (NOT Atom) has lost one electron , so there are now 11 protons(+), and 10 electrons(-). Hence 11(+)10(-)= 1(+) Hence the sodium ion is written as 'Na(+)'.
If you dont know this answer , well i dont either :0
Sodium Sulfate is Na2SO4 and so there are 7 atoms in the molecule.
Every single atom of sodium has exactly 11 protons in the nucleus.
