like to be in pairs (Parli exclusion Principle)
lowest energy

want to be in their state to
maintain stability
·
more stable :
less reactive
Coulomb's law
I
greater charges result
in a stronger force .
"
electrostatic model increased distance
between charges
weakens the force
opposites attract like charges
repel. negative atoms want
stability
to find positive charges .
i
charge wants to delocalize .
if it is distributed over a
greater area , we increase
delocalization will

why do atoms bond ?
2 &
negative likes positive
He is at its lowest energy when bonded and
therefore is able to maintain stability when
bonded .
why notHer or C? quantum mechanics

Werner Heisenberg's electron 35
theory (the uncertainty principle) :
we don't know exactly where the electron
is it's
or where going
