What compounds end in ate or ite?
The -ite ending indicates a low oxidation state. Thus,the NO2- ion is the nitrite ion. The -ate ending indicates a high oxidation state. The NO3- ion, for example, is the nitrate ion….Naming Positive Ions.

How do you know which suffix to use 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.
What does the suffix IDE mean in chemistry?
Definition of -ide (Entry 2 of 2) 1 : binary chemical compound —added to the contracted name of the nonmetallic or more electronegative element hydrogen sulfide or group cyanide. 2 : chemical compound derived from or related to another (usually specified) compound anhydride glucoside.
What does IDE ITE ate mean?
The name of an ionic compound ends in: -ide if it contains just two elements. -ate if it contains three or more elements, one of which is oxygen.
How do you know when to use IDE ate or ite?
-ide is used for non-metal compounds generally. For example, Chlorine forms a chloride ion, so NaCl is Sodium Chloride. -ate and -ite are commonly used for polyatomic ions of Oxygen. -ate is used for the ion that has the largest number of Oxygen atoms.
How is the suffix IDE used with an anion?
Explanation: In naming ionic compounds, the name of the metal cation (positively charged) usually goes first followed by the name of the nonmetal anion (negatively charged). The suffix -ide is only used if the nonmetal anion is monoatomic (meaning one atom).
Why do elements end in IDE?
The -ide ending is added to the name of a monoatomic anion of an element. Some polyatomic anions contain oxygen. These anions are called oxyanions. When an element forms two oxyanions, the one with less oxygen is given a name ending in -ite and the one with more oxygen is given a name that ends in -ate.
What does the ATE suffix mean?
-ate. noun suffix (2) Definition of -ate (Entry 4 of 6) 1 : office : function : rank : group of persons holding a (specified) office or rank or having a (specified) function vicarate. 2 : state : dominion : jurisdiction emirate khanate.
Do all chemical compounds end in IDE?
Single-atom negative ions end in “-ide”, so binary compounds always have this ending. Polyatomic compounds usually end in “-ate” or “-ite”. Subscript on H always follows the charge on the negative ion. NAMES: First word is a numerical prefix (omitted if first element occurs only once), then name of first element.
What does ate mean in chemistry?
2 Answers. ‘Ate’ is not a specific word. It is a suffix (an affix that is placed at the end of a word) when naming chemical substances. The suffix ‘ate’ is most commonly used when naming esters, for example, nitrate, sulfate etc. The suffix of a chemical substance is usually indicative of its oxidation state of an atom within a polyatomic ion.
What does IDE mean in chemistry?
Again, “ide” usually means there’s just two elements combined. Remember the “ide” means this is a compound made from two elements, in this case sodium and chlorine.
What is the difference between ATE and ITE?
The hard rule here is -ate always has one more oxygen than -ite. Look at how each -ate and -ite are organized so that you could compare easily. However, -ate DOES NOT always mean it has three oxygens and the ending -ite does not always mean it has two oxygens.
-ide in Science. A suffix used to form the names of various chemical compounds, especially the second part of the name of a compound that has two members (such as sodium chloride ) or the name of a general type of compound (such as polysaccharide).
