Molecular solid
What type of solid is Mg?
Metallic solid
Opposite charges…
Attract
Alike charges…
Repel
True or false: Ionic solids are malleable (can bend + shape)
False
Can ionic solids conduct electricity?
They cannot when they are a solid crystal due to its ions not being able to move freely to carry an electric charge.
What happens when ionic solids/compounds are melted or dissolved in water?
The liquid of the ionic compound conducts electricity due to the ions being able to move freely.
Melting point
Temperature at which a solid substance turns into a liquid.
Boiling point
Temperature at which a liquid substance turns into a gas
Strong/weak attractive forces…
Hold the substance’s particles together.
Lots of heat/not a lot of heat are required…
To overcome the attractive forces within the substance
Lewis Diagrams
Shows how the atoms in a molecule bond to each other with non-bonding & bonding electrons
