there is no such element
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.
No, metals typically have fewer valence electrons compared to nonmetals. Valence electrons are the outermost electrons in an atom, involved in bonding and determining the reactivity of an element. Metals tend to have fewer valence electrons which allows them to easily lose electrons and form positive ions.
all elements from group 16 or the chalcogens (oxygen, sulphur, selenium, tellurium and polonium)
Because it has a fourth shell which means it's valence electrons are further from the nucleus (protons) meaning that there is less attraction between it's electrons and protons; this obviously forms a weaker bond. Sodium has only 3 shells which means its valence electrons are closer to the nucleus.

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.
Cl Chlorine
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).
This would be Sb - Antimony.
The element described would be phosphorus. Phosphorus has 5 valence electrons (more than oxygen) and 15 protons (more than sodium but fewer than argon).
The gaseous element with 5 valence electrons and fewer neutrons than sodium is Boron. Boron has 5 protons and 5 neutrons, while sodium has 11 protons and about 12 neutrons.
No, an element's reactivity is mainly determined by the number of electrons in its outer shell, known as valence electrons. Elements with fewer valence electrons tend to be more reactive as they seek to either lose, gain, or share electrons to achieve a stable electron configuration. The number of protons in an atom, which determines the element's identity, does not directly influence its reactivity.
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).
