What element has more valence electrons than oxygenfewer valence electrons than neon more protons than sodium but fewer protons 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.


Element that has more valence electrons than oxygen fewer valence electrons than neon more protons than sodium but fewer protons 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).


Which has more valence electrons atom or aluminum or phosphorus?

Aluminium has three valence electrons and phosphorous has five, hence the latter has more.


What has more valence electrons than oxygen?

All halogen elements have 7 valence electrons (group 17): F, Cl, Br, I, At.


Does neon or oxygen have more valence electrons?

Neon has more valence electrons than oxygen. Neon has a full outer shell with 8 valence electrons, while oxygen typically has 6 valence electrons.

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.


Which has more valence electrons potassium or calcium?

Calcium has more valence electrons than potassium. Potassium has only 1 valence electron, while calcium has 2 valence electrons.


What element has more valence electron that oxygen few valence electrons than neon more protons than sodium but fewer protons than argon?

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.
