The maximum number of electrons that can occupy a valence shell.

The valence shell levels fall into two groups.

A bond is formed when the valence shells of two atoms overlap.

They are always in the last shell of an atom, the valence shell.

One characteristic that all do have in common is having three electrons in their valence shells.

A carbon atom has four electrons in its outermost valence shell.

Noble gases are very stable and unreactive because they have complete valence shells.

Period 1 elements follows the duet rule, they only need two electrons to complete their valence shell.

They are highly reactive due to the presence of unpaired valence shell electrons.

The valence shell is the outermost shell of an atom.

This is due to the metal having different valency states that have fewer or greater electrons in the valence shell.

Note Cl in this compound formally has a decet (10e) valence shell.

One Magnesium requires two Cl to satisfy its valence shell.

But in the valence shell of silver atoms, there is a single electron whose spin remains unbalanced.

Atoms that have an almost full or almost empty valence shells tend to be very reactive.

Electricity introduces the electrons necessary to complete the valence shells of the elements that, in turn, form more stable compounds.

Hydrogen is an exception to the octet rule because it only requires 2 electrons to complete its valence shell.

Each atom is thereby able to complete its valence shell and attain a stable noble gas configuration.

The s-sub-shell in the valence shell is represented as the ns sub-shell.

In metallic bonds valence shell electrons are delocalized and shared between many atoms.

Fermi asked her to investigate the valence shell of the undiscovered transuranic elements.

The osmium atom has eight valence shell electrons.

Cations are positively-charged ions that have given up one or more electrons from the valence shell.

Metal atoms contain few electrons in their valence shells relative to their periods or energy levels.

Like cobaltocene, decamethylcobaltocene has a 19 electron count in its valence shell and is paramagnetic.
