A stable atom has 8 electrons in its outer most valence shell. A simple way to remember this is that all atoms want to be like the noble gases which all have 8 electrons (except helium but the reason is complicated and not necessary here)
A stable atom has its outermost energy level completed with the maximum amount of electrons.
A stable electron has 8 or zero valence electrons
A stable element has to have at least 2 valence electrons. But it can vary.
All stable atoms have 8 valence electrons except for Hydrogen and Helium who have 2. If the atom doesn't have enough then they can share electrons with the other atoms.
if an atom has 8 valence electrons (obeying octet rule) then it is stable.
It depends on the atom. List what element the atom is from.
Here are 16 valence electrons: 3 from H, 8 from O and 5 from P.
8 - called valence electrons. it doesn't matter what energy level or orbital shape. a "happy atom" has 8 valence electrons

Electrons 'jump' from one atom to another. The electron configuration of the atoms determine how easy it is for an electron to move from one atom to another, which is a factor in determining conductivity of the substance.Actually in atoms in the solid state, electrons occupy one of 2 quantum energy bands: the valence band or the conduction band. Valence band electrons are tightly bound to the atom, but conduction band electrons are not bound to the atom and can roam freely through the material.insulators have very few if any conduction band electrons and thus cannot conductconductors have so many conduction band electrons that they form what is called an electron gas that fills all of the material and can flow freely, there is no"'jumping' from one atom to another" at all
Only when their outer shell is saturated>>>>>>>>>>>>
8 valence electrons
you would need a full outer shell so 8
Oxygen has six valence electrons.
All atoms want to have their outer energy levels full. When they have eight valence electrons they are full. They will become full by combining with other elements that the they may encounter until they see eight. You also could say until they have eight valence electrons.
An atom requires 8 valence electrons to be chemically stable. The elements with 8 valence electrons are the Noble Gases, and they are both stable and largely unreactive.
8 are traditionally needed in the valence shell.
Gallium is a mono-atomic metal element. So their atoms are atoms, and as many as you have!
8 valence electrons
Aluminum has 3 valence electrons.
Four.
