Answer:
The amount of gravity they have depends on their size. So, a small planet has less and a larger planet has more gravity. Just like the planets, a person with more mass has more gravity and therefore weighs more.
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.
