In its ground state, sodium (Na) has one more electron than neon sodium, although elements are defined by the number of protons in the nucleus rather than electrons in orbit around the nucleus. in a neutral atom, there is always one electron to every proton.
The element described has more valence electrons than oxygen but fewer than neon, more protons than sodium but fewer than argon. This element is magnesium, which has 12 protons, 12 valence electrons (2 more than oxygen but 2 less than neon), and is situated between sodium and argon on the periodic table.
The element described is chlorine. It has 7 valence electrons, which is more than oxygen but fewer than neon. Chlorine has 17 protons, more than sodium but fewer than argon.
The element in question is magnesium. It has 12 protons (more than sodium and less than argon), 2 more valence electrons than oxygen (which has 6), and 8 fewer valence electrons than neon (which has a full valence shell with 8 electrons).
The element that fits these criteria is sulfur. Sulfur has 6 valence electrons (more than oxygen with 6, fewer than neon with 8), 16 protons (more than sodium with 11, fewer than argon with 18).
The element described would be phosphorus. Phosphorus has 5 valence electrons (more than oxygen) and 15 protons (more than sodium but fewer than argon).
Neon has 0 valence electrons so it is not possible to have an element with fewer valence electrons. There can, therefore, be no such element.

The element that fits these criteria is sulfur. Sulfur has 6 valence electrons (more than oxygen with 6, fewer than neon with 8), 16 protons (more than sodium with 11, fewer than argon with 18).
The element described would be phosphorus. Phosphorus has 5 valence electrons (more than oxygen) and 15 protons (more than sodium but fewer than argon).
Neon has more valence electrons than oxygen. Neon has a full outer shell with 8 valence electrons, while oxygen typically has 6 valence electrons.
Although neon has more valence electrons than sodium, the size of an atom is primarily determined by the number of electron shells. Neon's higher nuclear charge causes its valence electrons to be held more tightly, resulting in a smaller atomic size. Sodium, with fewer valence electrons, has a larger atomic size due to less nuclear charge and more electron shells.
Neon has 8 more protons and 8 more electrons than helium. It's heavier, but still lighter than air.
