What is the difference between effective valence electron and outer shell count?

∙ 12y ago
Number of electrons in outer shell determines thechemical nature of the element and is unique per element. Effective Valence electrons is a calculated ratio between two concentrations of electrons. if n=resisitivity/(e*driftMobility)
and n_at=density*Avogadro#/AtomicMass. Effective valence electrons is then n/n_at. Rounding this number should agree with outer shell electrons as predicted from the Periodic Table.

Why do the valence electrons in nitrogen experience a greater effective nuclear charge than the valence electrons in beryllium?
valence electron in nitrogen
What is the difference between the arrangement of electrons in sulfur and chlorine?
Chlorine has one more electron then sulfur, so it has 1 more electron in the outer shell, 1 more valence electron. Chlorine has 5 electrons in the outermost shell and sulfur has 4.
How many valence electrons does the element cesium have?
A cesium atom has 1 valence electron. It is an alkali metal, and all alkali metals have 1 valence electron. The electron configuration for cesium is (Rn)7s1. The single electron in the 7s sublevel is its valence electron.
How many valance electrons does hydrogen have?
Hydrogen has only one electron. Just the one. And it is a valence electron.
How many valence electrons does an atom of potassium have?
4
What is the difference between a electron and a valence electron?
While electrons can be on any layer, a valence electron is an electron that is found in the outermost layer of an atom and that determines the atom's chemical properties.
What is the difference between a valence electron and a shielding electron?
Valence electrons are electrons on the outermost shell/orbitals. Sheilding electrons are inner electrons that block valence electrons from protons causing less attraction.
What is the approximate effective nuclear charge for a valence electron in krypton?
2
Why do the valence electrons in nitrogen experience a greater effective nuclear charge than the valence electrons in beryllium?
valence electron in nitrogen
What is the difference between potassium and aluminum?
potassium belongs to group 1 and has one valence electron. aluminium belongs to group 13 and has three valence electrons.
Why effective mass of electron is negative at the top of valence band?
Because of holes
Does H and HE have the same valence electron configuration?
Hydrogen and helium have different valence electron configurations. Hydrogen has one valence electron, and helium has two valence electrons. However, hydrogen does typically form covalent bonds in which it shares an electron, and thereby gains an effective electron configuration of two, like helium. Hydrogen also can form the H+ ion which has no electrons.
What is the difference between the Lewis model and the valence-shell electron pair repulsion model?
VSEPR only shows the geometric shape of the element
What is the difference between alkali metal and group 2 metals?
Alkali metals have one valence electron, group 2 metals have 2.
What do valence electrons determine about an element?
they determine the difference between the elements like a hydrogen atom has 1 electron and carbon has 6
What is the difference between the Lewis model and the valence-shell electron pair repulsion (VSEPR) model?
VSEPR only shows the geometric shape of the element
What is the functions of valence electron?
Valence electrons are the ones that are used in bonding between atoms.love
