Its to do with the number of electrons in the respective elements outer shell. Phosphorus is in group 5 and therefore wants 3 more electrons to fill its outer shell. Oxygen is in group 6 and therefore wants 2 electrons per oxygen atom. A covalent bond is the sharing of electrons. We are trying to find a subscript value with means they both have full shells. Phosphorus trioxide isn't really phosphorus trioxide it is tetraphosphorus hexoxide . (tetra =4) (hex = 6).

First never use parentheses with an element, only with polyatomic ions. Ca has a +2 charge and Cl has a -1 charge but the charges must balance thus you need another Cl to get -2. +2 + -2 = 0, balanced. CaCl2

What if you are not given the prefixes in a covalent instance. In my textbook, it says that phosphorus chloride's formula is PCl3. I don't understand why there are three chlorides. Similar to hydrogen oxide (water) I know its simple but how do u find the covalent formular as H20 without prefixes.

It's not that you can't, it's just customary to remove the a from "ao" combinations. If you removed the "i" from dioxide you fundamentally change the meaning of the word. The "di" is important to the meaning. Remember science is not absolute. It's a set of general rules and ideas that have exceptions.

If your textbook is referring to PCl3 as phosphorus chloride, it is a poor textbook. How can you distinguish between PCl3 and PCl5? The reason there are usually three chlorine atoms on one phosphorus atom is because chlorine only has one bond and phosphorus has three bonds. Never call water hydrogen dioxide. Water is water. Check out my videos on Lewis dot symbols and oxidation.
