Is the prefix mono- used when naming the first element in a formula?

No. Prefixes designating quantity are only ever used for other elements in the compound, never the first one. Example: Carbon Monoxide. The chemical formula is CO, and there is one Carbon atom, just as there is one Oxygen atom, but the Mono- prefix is only affixed to the Oxygen.
It should be noted, however, that such prefixes are not always used in chemical formulas. MgCl2 is not named Magnesium Dichloride, just Magnesium Chloride.

What comes first in naming of covalent bonds?
When naming covalent bonds, you first put down the name of the first element. After that, you use a prefix for indicating the number of the atoms of the anion for which you use a suffix. Example: Carbon dioxide.
What is the chemical formula for dicarbon hexahydride?
The formula for dicarbon dehydrate is C2H2. Remember that the prefix di means two and the rules for naming covalent compounds. First element is named using its name. The second is named as an aniond with the suffix -ide. Prefixes are used to denote the number of atoms of each element, except for mono.
In a formula for an ionic compound which element comes first?
The more or most electropositve element.
Do you use the prefix mono for the first element of a binary covalent compound?
No, you do not. The prefix -mono in front of the first element of a binary covalent compound is dropped. For example, if we take the molecular compound CO, we do not call it "Monocarbon Monoxide". It is called "Carbon Monoxide".
When is it appropriate to use prefixes when naming compounds?
Almost always. Especially when there are more than one atom of the first element in the compound.

How do you know which element comes first in a molecular formula?
The more or most electropositve element comes first.

When naming a compound what gets changed about the first element?
That depends on whether it is an ionic or covalent compound. If ionic, the first element has the same name as the element or ion, e.g. NaCl is sodium chloride; NH4Cl is ammonium chloride. If the compound is covalent, then the first element either retains its original name or has a prefix to denote the number of atoms of that element. For example, CO2 is carbon dioxide; P2O5 is di phosphorous pentoxide.
When is it appropriate to use prefixes when naming compounds?
Almost always. Especially when there are more than one atom of the first element in the compound.
What is the covalent compound formula for iodine Pentagon fluoride?
The molecular formula for iodine pentafluoride is IF5. No prefix in front of iodine is understood to be one, but mono- is not used for the first element in a binary covalent compount. The prefix penta- means five, so the subscript for fluoride is 5. Unfortunately, there is no way to write the 5 as a subscript.
When is a prefix not used in front of the name of an element?
No prefix is used if it is an ionic compound. If it is a binary molecular compound, the prefix mono- is not used in front of the name of the first element. For example, the ionic compound Na2O is sodium oxide, not disodium monoxide, and the molecular compound CO2 is carbon dioxide, not monocarbon dioxide.
When naming a ray the endpoint is written first?
When naming a ray the endpoint is written first.
What is the chemical formula of the first carbohydrate molecule?
CHO is the element symbol if that's what you mean
How did the first naming systems work?
The first naming system worked through a process of naming system called binomial nomenclature.It has two parts :GENUSSPECIES
