Calcium is a group 2 element, and so it will form a cation, Ca 2+.
what do you expeat to find in calcium chloride in ocean water
Not by themselves, because they are both too electropositive. Together with oxygen, however, they form calcium aluminate.
Ca+2
The bond between calcium and sulfur would be ionic. The corresponding compound would be calcium sulfide.
Calcium most likely will react with the oxygen in the air. 2Ca(s) + O2(g) -->2CaO(s). It would form solid calcium oxide.
if done in water solution, the extracted calcium would immediately react with the water to form calcium hydroxide.

No calcium is needed
Calcium Chloride
They would form an ionic bond. Calcium is a metal and oxygen is a non-metal, and the ionic bond is the most common way these two types of elements get together. Calcium has 2 valence electrons, which it will lose to oxygen, which has 6 and therefore needs 2. Calcium and oxygen will combine in a 1:1 ratio to form calcium oxide with the formula CaO.
It turns a bright red color and it does not spread. If you take a little bit of calcium and put in a bowl and light it up, it will crete a small fire in the bowl but it will not burn it.
