Ionic bond
Explanation:
Ca - Cl₂ is an ionic bond because it involves a true metal and a non-metal.
An ionic bond is an inter-atomic bond between two chemical species.
- This bond forms between two atom with a large electronegative difference.
- Often times, this corresponds to a metal and a non-metal.
- The metal is the less electronegative specie and the non-metal is more electronegative
- The metal such as Ca loses two electrons to become positively charge ion.
- The non-metal gains the electrons. Here two atoms of Cl are turned to ions.
- Electrostatic attraction between the metal and non-metal forms the ionic bonding.

Assuming that the space within the solid or liquid is vacuum, it is not matter because there is no mass inside. However, there is a volume. The volume inside a solid would have regular straight sides because atoms of a solid is compactly arranged. For liquids, the space could be irregular curves and paths because the atoms in a liquid are free-flowing.
