When a substance contains more than one kind of atom, then we say that it is a compound. We all know that a chemical element has one type of atom only. The suffix "ic" is used when the acid has more oxygen atoms. We use the suffix "ic" or "ous" while naming them. For instance, HF is called hydrofluoric acid and HCl is named as hydrochloric acid. The prefix "hydro" and the suffix name"ic" are used to name hydro acids. For instance, is named as sodium sulphate and is called sodium sulphite. Most of the compounds containing polyatomic ions end with "ate" or "ite". In a polyatomic ion, the atoms are generally covalently bonded to each other. For instance, has one nitrogen atom and four oxygen atoms. Polyatomic ions contain more than one atom. The rules for naming ionic compounds containing polyatomic ions are different. Naming Ionic Compounds that Contain Polyatomic Ions ![]() Step 4: Check if any prefixes are required Because there are no ionic charges to balance out molecular compounds, therefore you should use prefixes shown in the table below:įor instance, is named as carbon dioxide and CO is named as carbon mono oxide. For instance, FeCl is named as iron (I) chloride and is named as iron (II) chloride. If you have ionic compounds with transition metals, then you should add a roman numeral after the metal name to show the transition metal's charge. Step 3: Check if you require roman numerals Look for an ionic compound that has a transition metal that becomes a multivalent ion. For instance, if the second compound is chlorine, then you should remove "ine" and replace it with "ide", so that we can spell it "chloride". This rule is same for molecular or ionic compounds. Step 2: To the end of the second compound's name, add the word "ide" After you have determined a molecular or ionic compound, the next step if to look at the second compound and replace the last three words with "ide". Nonmetals are present on the right side of the periodic table above the staircase, including hydrogen) The compound is molecular if it contains two nonmetals.Metals are present on the middle and left side of the periodic table. The compound is ionic if it contains a metal.To do so, you should know what ionic and molecular compounds are. Here are the simple steps to name compounds in chemistry: Step 1: Determine whether the compound in an ionic or molecular compound The first step is to identify whether the compound you are going to name is an ionic compound or a molecular compound. Rules for Naming Ionic or Molecular Compounds There is a standard method of naming chemical compounds that is employed by all the scientists worldwide. Now, the question arises how these compounds are named in chemistry? The answer is simple. The properties of compounds are different than those of the elements that were used to make those compounds. You can easily search the list of compounds online. Do you know how many compounds are there? The answer is that there are more than 350,000 chemical compounds that are registered for use and production. The chemical bonds between the compounds are strong enough to make them act like a single substance. The elements that are joined together through chemical bonds are known as chemical compounds. On the other than, Nitrate has a larger number of Oxygen atoms so when added to an element it is _ Nitrate Share your tips and advice for learning the names of chemical compounds in the comments. ![]() Nitrite has a smaller number of oxygen atoms so when added to an element it will be _ Nitrite. NO2 and NO3 are known as Nitrite and Nitrate respectively. The -ite would be used for the ion with the smaller. ate is used for the ion that has the largest number of Oxygen atoms. ate and -ite are commonly used for polyatomic ions of Oxygen. For example, Chlorine forms a chloride ion, so NaCl is Sodium Chloride. ide is used for non-metal compounds generally. How do you know whether to use 'ide' or 'ate', when naming a compound? For example:įor a more in depth explanation check out this video. When naming molecular compounds prefixes are used to dictate the number of a given element present in the compound. Naming compounds is important to allow scientists to identify and recognize the different compounds. Chemical nomenclature is the process of naming compounds.
