SHAPES OF MOLECULES & IONS
The shape of a molecule/ion depends on the
number of electron pairs in the outer shell of
the central atom.
Electron pairs repel each other and try to
get as far apart as possible.
Species containing only bonding pairs of
electrons have regular shapes.
This is because bonding pairs of electrons
exert equal repulsion on each other.…read more
SHAPES OF MOLECULES
The shape of a molecule/ion ALSO
on the presence of non-bonding electron
pairs (lone pairs).
Lone pairs take up more space (because they
are held closer to the nucleus) so repel more
strongly than bonding pairs…read more
