Almost always. Especially when there are more than one atom of the first element in the compound.
No, formulas of ionically bonded compounds can be figured out without prefixes and understanding of how many electrons are gained/lost. In covalent bonds, prefixes are needed and without them the formulas and quantities couldn't be determined.
Ions combine in only one ratio, so prefixes are not needed.
yeah.. mono-1 di-2 tri-3 tetra-4 penta-5 hexa-6 hepta-7 octa-8 nona-9 deca-10 dodeca-20 The real answer is NO. The prefixes are only used in Type III compounds which are Covalent Bonds. Ionic Bonds only need the ending -ide.
Some types of compounds that use prefixes in their names are covalent compounds, particularly binary covalent compounds formed between nonmetals. These prefixes indicate the number of atoms of each element present in the compound. Examples include carbon dioxide (CO2) and dinitrogen tetroxide (N2O4).
When naming organic compounds with multiple functional groups, identify and prioritize the functional groups based on their seniority. The compound name should reflect the highest priority functional group as the main chain, with other functional groups indicated as substituents using prefixes or suffixes. Use prefixes like di-, tri-, etc., to indicate multiple occurrences of the same functional group. Be sure to follow the rules of nomenclature set by the International Union of Pure and Applied Chemistry (IUPAC) for accurate and systematic naming.

You use it on every single element
Ions combine in only one ratio, so prefixes are not needed.
Covalent compounds, particularly binary compounds consisting of two nonmetals, use prefixes in their names to indicate the number of atoms of each element present in the molecule. This helps distinguish between similar compounds with different ratios of atoms.

When naming compounds, follow these general rules: for ionic compounds, the metal name is written before the nonmetal name with an -ide ending (e.g. sodium chloride); for covalent compounds, use prefixes to indicate the number of atoms of each element (e.g. carbon dioxide). For writing chemical formulas, the element symbol is used with subscripts to indicate the number of atoms of each element present in the compound. Remember to balance the charges to ensure a neutral compound.
The appropriate metric prefix is centi- for 10-2
two ions can combine in only one combination
FeCl2 and BaCl2 do not use prefixes in their names because iron (Fe) and barium (Ba) can only have one charge in these compounds, making it unnecessary to indicate the number of each element with a prefix in their names. The charges of Fe and Ba in these compounds are fixed, so the stoichiometry can be determined without the use of prefixes.
I assume you're talking about prefixes in chemistry. When naming covalent, or molecular compounds, prefixes are necessary because there are different ways that the non-metals can bond with other non-metals. Here are the prefixes most often used in covalent compounds: mono=1 di=2 tri=3 tetra=4 penta=5 hexa=6 hepta=7 octa=8 nona=9 deca=10. For example, N2O4 is "dinitrogen tetroxide." *A noteworthy exception: if there's only one of the first atom, you DON'T use the mono-prefix; you simply don't use a prefix. Example: carbon monoxide means one carbon, one oxygen.
