Default Question about ions



First of all, equilibirum is not 50% - 50%

If you are studying chemical bonding, you must have passed by Electron
Affinity,
Ionisation Potential and Electronegativity (which depends upon the first
two).

*All* elements will have a positive ionization potential, which means that
*no*
element wants to lose electrons.

On the other hand, *all* elements have a positive electron affinity (with
two definite
exceptions and excluding noble gases), which means that *all* elements would
accept an extra electrons, but...

As another poster wrote, the enviroment will be the most important factor.

If two atoms are put togheter and one fo them has a really high electron
affinity,
this atom will "try" to steal on electronfrom the other atom. Depending upon
the
Ionisation potential of the fromer, it will not be strong enough to hold its
electron,
and will ionise.

This balance of electron affinity and ionisation potential is best described
by electronegativity.

The octet rule is just an aproximation with lots of exceptions...
