The Electron Structures of Ions and Noble Gases are the Same.
gases are in group 0 of the
They will not react with other atoms because they have
a full outer shell of electrons and no overall charge.
which have lost or gained electrons to
have a full outer shell of electrons but because they have a charge
they will form ionic bonds with other oppositely charged ions.
Ions and noble
gases both have a full
outer shell of electrons
and therefore can have the same electron structure.
A Li+ ion has the same electron structure as Helium.
A Mg2+ ion has the same
as a Na+ ion and a O2- ion.
It is the electron structure of Neon (see previous pages).
A Cl- ion has the same electron structure as Argon.
Helium is 2.
Neon is 2, 8.
Argon is 2, 8, 8.
Ions are said to have a noble gas electron structure.
