You use the criss cross method to swith the charge of the element with the charge of the whole ion
If the charge of the element is more than one then put the ion in parenthesis and then put the charge outside
Symbols are given to elements. Formulas describe compounds. Petroleum contains up to 3,000 different compounds, many in very small quantities. Further, every field has a unique mixture of compounds, so no one formula would work. See link.
Yes, metallic bonds are polyatomic, in the sense that all the atoms in a given piece of metal share a bond, it's not just a bond between adjacent atoms, as in other types of bonding such as ionic or covalent.
The elements and compounds to the right of the equations are called products.

No, they should always not be. As an example, NaOH can be given.

You can treat a polyatomic ion as an element when balancing equations. The following example involves the polyatomic ion NO3-. Notice that the entire polyatomic ion is placed in parentheses and given its own subscript. 2Al(s) + 3Mg(NO3)2(aq) --> 2Al(NO3)3(aq) + 3Mg(s)

compounds
In general, it's impossible to know ahead of time how much of compound A and how much of compound B might be in a particular mixture of A and B. The mixture doesn't have any given chemical formula, because sometimes it might be mostly A with some B and sometimes it might be almost all B with only a tiny bit of A. There's one exception to this: Sometimes you'll see formulas given for mixtures where the proportions are known, e.g. a particular mineral might have a "formula" of Ca(0.8)Mg(0.2)CO(3) where the numbers in parentheses represent subscripts.
