Elements with more than four valence electrons are typically found in groups 14 to 16 of the Periodic Table. For example, carbon (with four valence electrons), silicon, germanium, and elements like nitrogen (five), oxygen (six), and fluorine (seven) fall into this category. These elements often exhibit a higher tendency to form covalent bonds, leading to diverse molecular structures and compounds. They play critical roles in organic chemistry and various biological processes.
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.
there is no such element
Chlorine.
all elements from group 16 or the chalcogens (oxygen, sulphur, selenium, tellurium and polonium)
The maximum number of valence electrons an element can have is 8. This is because the outermost energy level, or valence shell, of an atom can hold a maximum of 8 electrons. Exceptions to this rule can occur for elements that can have more than 8 electrons in their valence shell through the process of expanded octet.
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 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 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 described would be phosphorus. Phosphorus has 5 valence electrons (more than oxygen) and 15 protons (more than sodium but fewer than argon).
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.
Cl Chlorine
If an element has less than four valence electrons, it will tend to lose its valence electrons and form cations. If an element has more than four valence electrons, it will tend to gain electrons and form anions. An element that has four valence electrons will tend to form covalent bonds rather than ionic bonds.
This would be Sb - Antimony.

Compounds have more than one kind of element.
