Chlorine
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 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.
Oxygen has 8 protons- the atomic number is the number of protons an atom has. A single oxygen atom contains 8 electrons to balance this charge, but oxygen is diatomic- meaning it will be O2 instead of just one Oxygen molecule.
Oxygen is the element that has 8 valence electrons and is in the gaseous state at room temperature.
there is no such element

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.
Sulfur, which is in the oxygen family, has 6 valence electrons.
oxygen is a element one the periodic table, as such it is made up of protons electrons and neutrons. so there are protons in oxygen but there is not oxygen in protons.
Oxygen has 8 protons- the atomic number is the number of protons an atom has. A single oxygen atom contains 8 electrons to balance this charge, but oxygen is diatomic- meaning it will be O2 instead of just one Oxygen molecule.
Oxygen is the element that has 8 valence electrons and is in the gaseous state at room temperature.
The element with 8 protons and 8 electrons is oxygen (O). The presence of 11 neutrons indicates a specific isotope of oxygen, oxygen-19.

Calcium oxide (CaO) consists of calcium (Ca) and oxygen (O). Calcium, a group 2 element, has 2 valence electrons, while oxygen, a group 16 element, has 6 valence electrons. Therefore, in total, CaO has 2 (from Ca) + 6 (from O) = 8 valence electrons.
