When main group elements react, they tend to acquire eight outershell electrons nsnp
This is called an octet, and it is a particularly stable configuration.
Group Valence To attain octet
ns
lose one electron
ns
lose two electrons
nsnp
lose three electrons
nsnp
gain three electrons
nsnp
gain two electrons
nsnp
gain one electron
nsnp
rarely gain or lose electrons
Nonmetals in the third period and beyond can break the octet rule because they have vacant d orbitals that allow them to accommodate more than eight outershell electrons.If the following elements were involved in redox reactions, which noblegas configuration would they most likely attain?
