What does the prefix represent for an element in a molecule?
a numerical prefix indicating the number of atoms of the second element, plus. the stem of the element name (e.g., ox for oxygen, chlor for chlorine, etc.), plus. the suffix -ide.
What are the 10 prefixes in chemistry?
Naming molecules in chemistry

| 8 | Octa- |
| 9 | Nona- |
| 10 | Deca- |
What makes up an ionic compound?
Ionic compounds are compounds composed of ions, charged particles that form when an atom (or group of atoms) gains or loses electrons. (A cation is a positively charged ion; an anion is a negatively charged ion.) Covalent or molecular compounds form when elements share electrons in a covalent bond to form molecules.
How do you use prefixes in chemistry?
When naming molecular compounds prefixes are used to dictate the number of a given element present in the compound. ” mono-” indicates one, “di-” indicates two, “tri-” is three, “tetra-” is four, “penta-” is five, and “hexa-” is six, “hepta-” is seven, “octo-” is eight, “nona-” is nine, and “deca” is ten.
Is ate always 3?
Under IUPAC rules it’s always “-ate” and if ambiguity could result (more than one common oxide) the oxidation state is given. Generally, however, if you’re just doing things where there are two types, one with one more O than the other, we’ll use “-ite” and “-ate” for them.
What does Hypo mean in chemistry?
The prefix hypo- is used to indicate the very lowest oxidation state. The ClO- ion, for example, is the hypochlorite ion. The prefix per- (as in hyper-) is used to indicate the very highest oxidation state. The ClO4- ion is therefore the perchlorate ion.
What are the 20 prefixes in chemistry?
Organic Chemistry Prefixes
| Prefix | Number of Carbon atoms | Formula |
|---|---|---|
| heptadec- | 17 | C17 |
| octadec- | 18 | C18 |
| nonadec- | 19 | C19 |
| eicosan- | 20 | C20 |
What are the 12 prefixes in chemistry?
Rules for Naming Molecular Compounds: ” mono-” indicates one, “di-” indicates two, “tri-” is three, “tetra-” is four, “penta-” is five, and “hexa-” is six, “hepta-” is seven, “octo-” is eight, “nona-” is nine, and “deca” is ten. If there is only one of the first element, you can drop the prefix.
What type of compound involves prefixes?
Molecular compounds are named using a systematic approach of prefixes to indicate the number of each element present in the compound.
What are some common prefixes in chemistry?
Some of the more common prefixes used in engineering, chemistry, materials properties etc. are giga, mega, kilo, milli, micro and nano . Example of usage for the base unit of the metre or 1m.
What are rules for prefix in a compound?
Rules for Naming Molecular Compounds: Remove the ending of the second element, and add “ide” just like in ionic compounds. When naming molecular compounds prefixes are used to dictate the number of a given element present in the compound. If there is only one of the first element, you can drop the prefix.
What does the prefix per mean in chemistry?
per-. 1. Prefix meaning through; denoting intensity. 2. chemistry More or most, with respect to the amount of a given element or radical contained in a compound; the degree of substitution for hydrogen, as in peroxides, peroxy acids (e.g., hydrogen peroxide, peroxyformic acid).
What is the prefix for chemical?
In chemical nomenclature, nor- is a prefix to name a structural analog that can be derived from a parent compound by the removal of one carbon atom along with the accompanying hydrogen atoms. The nor-compound can be derived by removal of a CH.
