Bonding
Ionic Bonding
When metals react with nonmetals, electrons are transferred from the metal
atoms to the non-metal atoms, forming ions
...
n
magnesium + oxygen → magnesium oxide
calcium + chlorine → calcium chloride
In both of these reactions, the metal atoms give
electrons to the non-metal atoms
...
Molecules Containing
Double Bonds
Some molecules contain a double or triple bond
...
There is a strong electrostatic force of
attraction between these oppositely charged
ions – this is called an ionic bond
...
Look at the diagram to the right showing the covalent bonding of H20 in a
dot and cross model
...
The
electrons involved are in the outer shells of
the atoms
...
Covalent bonds are strong – a lot of energy
is needed to break them
...
These substances have
strong covalent bonds within the
molecules (between the atoms), but weak
intermolecular forces between the
molecules
...
