Sodium is an element itself, it has no elements inside.
What makes each element unique is the number of protons in the nucleus. Sodium has 11 protons and Magnesium has 12 protons. The periodic table is arranged with the number of protons of each element increasing to the right and down the table. For an element to fit between sodium and magnesium it would have to have fewer than 12 protons but more than 11, which is simply not possible.
there is no such element
Because atoms can be isotopes or ions, protons are the only stable identifier for an element (Sodium can have more or less than normal number of electrons or neutrons and still be sodium). Sodium has 11 protons.
That number is based upon the number of protons found in the nucleus. -See the related link liste dbelow for more information.(It is not the number at which the atom may be reached...)
Elements are pretty much defined by the number of protons in the nucleus. This number (the atomic number) defines the element. All the different elements have different numbers of protons in their nucleus.

For sure the sodium atomic nucleus contains 11 protons. The natural isotope of sodium(23) also contains 12 neutrons, but other isotopes are possible with less or more of them in the nucleus. Still 11 protons, always!
Its atomic number. In other words the number of positive protons in the nucleus of each atom and the number of negative electrons surrounding the nucleus of each atom.

Sulfur. definitely Sulfur
When the atom gets bigger. Bigger atoms mean more protons in the nucleus. You can find out the number of protons by looking at a periodic table, it's the bottom number of each element. This is because the nucleus is positively charged (containing protons and neutrons) so the more protons there are, the more positively charged it will become.
That number is based upon the number of protons found in the nucleus. -See the related link liste dbelow for more information.(It is not the number at which the atom may be reached...)
It generally corresponds to the number of protons in its nucleus. In a neutral atom, this will also correspond to the number of electrons orbiting the nucleus; however, electrons are more likely to move around.
Each oxygen atom contains 8 protons in its nucleus. The atomic number of a chemical element (also known as its proton number) is always the number of protons found in the nucleus of an atom of that element, and identical to the charge number of the nucleus. It is conventionally represented by the symbol Z.
