bulky ones naje it hard for the chains to slide over each other and stack
together, which prevents the formation of crytalline regions that refract
light and amorphous materials are made.

- have a high melting and boiling point
- they're solid at room temperature
- are hard, but brittle, so they're not malleable or

materials on the nanoscale.
the prefix nano refers to... refers to one billionth or 10-9 in scientific notations.
metal atoms lose electrons to non metallic atoms
cation
and become positively charged metal ions
non metal atoms gain electrons from metal atoms
anions
and became negatively charged non metal ions
what forces result from electrostatic
the attraction between
positive and negative
charges
they have high melting points because a large
explain high melting amount of energy is needed to overcome the
points of ionic electrostatic attraction between the oppositely
compounds charges ions and allow them to move. So, the ionic
bonds between the + and - ions is strong.

a strong force is needed to
disrupt the crystal lattice,
which means that it's very hard.
Although a salt crystal is hard,
a strong force will shatter the
crystal, meaning it's brittle. This
explain hardness and is because layers of ions will
brittleness of ionic move relative to each other
compounds due to the force of blow.
During this movement, ions of
like charge shift so they are
next to each other. The
repulsion between the similarly
charged ions causes the crystal
to shatter
in solid form, ions are held in the crystal lattice and
are not free to move, therefore don't conduct
electricity. When solids melt, the ions become free
to move, enabling the cations and anions in the
explain electrical
molten compound to conduct electricity. When they
conductivity of ionic
dissolve in water, ionic bonds in the lattice break
compounds
and the ions are separated and move freely. When
an electric current is applied, + ions move towards
the - charged electrode and - ions move towards
the + charged electrodes
