The Electron Structure of Ions and Noble Gases are the Same.
The noble
gases are in group 0 of the
periodic
table.
They will not react with other
atoms
because they have
a full
outer shell of electrons
and no overall
charge.
Atoms
which have lost or gained electrons to
form ions
will also
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
electron structure
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.
The electron
structure of
Helium is 2.
Neon is 2, 8.
Argon is 2, 8, 8.
Ions are said to have a noble gas electron structure.
