In difluorine two additional electrons occupy the 2pπ with a bond order of 1.

Calculations show that the additional electron is located in the aluminium cluster at the location directly opposite from the iodine atom.

Hydrogen only needs one additional electron to attain this stable configuration, while lithium needs to lose one.

This releases additional electrons which are themselves accelerated and collide with further atoms, releasing more electrons, in a chain reaction.

Often tetrahedral complexes limited to form 4 additional bonds (8 additional electrons) by the 18-electron ceiling.

The central nitrogen atom has five outer electrons with an additional electron from each hydrogen atom.

The additional electron occupies an orbital that is anti-bonding with respect to the Co-C bonds.

But applying a positive electric field attracts additional electrons.

This stress results in additional pi-bonded electrons as opposed to radical or charged moieties.

The additional electron will be entering an orbital farther away from the nucleus.
