Do you use prefixes when naming ionic compounds?

When naming binary ionic compounds, name the cation first (specifying the charge, if necessary), then the nonmetal anion (element stem + -ide). Do NOT use prefixes to indicate how many of each element is present; this information is implied in the name of the compound.

Do you use prefixes when naming covalent compounds?

Rules for naming simple covalent compounds:

Name the non-metal furthest to the left on the periodic table by its elemental name.
Name the other non-metal by its elemental name and an -ide ending.
Use the prefixes mono-, di-, tri-…. to indicate the number of that element in the molecule.

Do you use prefixes when naming acids?

Acids are named by the anion they form when dissolved in water. When you have a polyatomic ion with one more oxygen than the “-ate” ion, then your acid will have the prefix “per-” and the suffix “-ic.” For example, the chlorate ion is ClO3–. Therefore, HClO4 is called perchloric acid.

What are the rules for naming an ionic compound?

Rules for naming simple ionic compounds.

Name the metal by its elemental name.
Name the nonmetal by its elemental name and an -ide ending.
Name metals that can have different oxidation states using roman numerals to indicate positive charge. Example Fe2+ is Iron(II)
Name polyatomic ions by their names.

Which element comes first in a covalent compound?

Answers. A covalent compound is usually composed of two or more nonmetal elements. It is just like an ionic compound except that the element further down and to the left on the periodic table is listed first and is named with the element name.

What is a the prefix we use to indicate 4 in covalent naming?

According to Table 2.6 “Prefixes for Indicating the Number of Atoms in Chemical Names”, the prefix for two is di-, and the prefix for four is tetra-.

What is the correct name for NI3?

Nitrogen triiodide is the inorganic compound with the formula NI3.

When do you use prefixes for molecular compounds?

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.

Which is the correct way to name a compound?

Do you use Greek prefixes when naming a compound?

Yes, the name for water using the rules for chemical nomenclature is dihydrogen monoxide. However, it is virtually never called that. When naming a binary molecular compound, the subscript for each element determines what prefix should be used. The following are the Greek prefixes used for naming binary molecular compounds.

When do you use prefixes to name an element?

3. Prefixes are used to denote the number of atoms 4. “Mono” is not used to name the first element
