Almost always. Especially when there are more than one atom of the first element in the compound.

Do you use the naming prefixes when naming ionic compounds?
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.
Types of compounds that use prefixes in their names are?
Prefixes in a name generally indicate the number of atoms of a certain element in a compound. For example, carbon dioxide has two atoms of oxygen and one atom of carbon.
Use complete sentences to explain why AlCl3 is called “aluminum chloride” (no prefix required), but BCl3 is called “boron trichloride.”?
Ionic compounds do not have prefixes but covalent compounds have prefixes. “Aluminum chloride” is a ionic compound and "boron tri-chloride” is a covalent compound.
Do Ionic compounds use prefixes mono di tri?
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.
Why must roman numerals be used when naming certain ionic compounds?
You must use roman numerals to indicate which oxidation state the element is in when that element is in a compound.
When is it appropriate to use Roman numerals when naming compounds?
You use it on every single element
Do you use the naming prefixes when naming ionic compounds?
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.
What types of compounds use prefixes in the names?
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.
Types of compounds that use prefixes in their names are?
Prefixes in a name generally indicate the number of atoms of a certain element in a compound. For example, carbon dioxide has two atoms of oxygen and one atom of carbon.
Use appropriate metric prefixes to write the following measurements without use of exponents 6.46 x 10-2?
The appropriate metric prefix is centi- for 10-2
Why use prefixes for molecular compounds?
two ions can combine in only one combination
Use complete sentences to explain why AlCl3 is called “aluminum chloride” (no prefix required), but BCl3 is called “boron trichloride.”?
Ionic compounds do not have prefixes but covalent compounds have prefixes. “Aluminum chloride” is a ionic compound and "boron tri-chloride” is a covalent compound.
What is the number associated with each prefix?
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.
Use appropriate metric prefixes to write the following measurements without use of exponents 12.5 x 10-8 kg?
125ug = 125 micro grams
Why do you use prefixes?
Prefixes are used in language to modify the meaning of a word. By attaching a prefix to a root word, we can create new words with different meanings. This allows us to be more specific in our communication and convey nuanced information.
Can you use the word naming in a sentence?
Do you know what you will be naming the baby?
What are molecule compounds?
Naming Binary Molecular CompoundsBinary molecular compounds are composed of only two elements. Examples are H2O, NO, SF6 etc. . Naming these binary compounds is a little bit more involved than naming salts. Why is this so? Molecular compounds are more difficult to name because the atoms combine through covalent and not ionic bonds. Therefore we cannot use the electrical neutrality rule for these compounds. Most molecular compounds are made from nonmetals. Sometimes these compounds have generic or common names (e.g., H2O is "water") and they also have systematic names (e.g., H2O, dihydrogen monoxide). The common name must be memorized. The systematic name is more complicated but it has the advantage that the formula of the compound can be deduced from the name. Simple binary compounds consist of only a few atoms. Systematic naming of these compounds follow the rules: * The elements , except for H, are are written in order of increasing group number (e.g., NO not ON) * The number of atoms of a given type is designated by a prefix such as di- , tri-, tetra- etc. (The exception to this rule is for the first atom: if the first atom is "mono" then no prefix for it is given.) (e.g., NO is nitrogen monoxide not mononitrogen monoxide)
