In chemistry, there are rules we must follow in naming ionic compounds. Rule 14 : Naming of Radicals Radicals are the side chains obtained from the removal of hydrogen from the corresponding hydrocarbon. Naming compounds is easy if you follow these 3 simple rules. Approved. With ionic compounds, the -ide suffix should be appended to the name of the nonmetal element, not the metal element. How do you name things like sulfuric acid and the other acids? Covalent compounds occur between non-metals. Examples: NaNO3 sodium nitrate Na2SO4 sodium sulfate CaCl2 calcium chloride K3PO4 potassium phosphate Asked by Wiki User. Ionic compounds consist of cations (positive ions) and anions (negative ions). The names of ionic compounds aren’t simply the names of both elements combined together without any change. The process of naming compounds is just a set of rules. When a compound has an oxygen removed or added, it changes into either an -ite or -ate compound. Second element is named as an Anion (suffix "-ide") 3. Ionic compounds are composed of metal and nonmetal elements. Top Answer. Menu. Rules for naming compounds.

Here are the principal naming conventions for ionic compounds, along with examples to show how … A substance that does not contain any water is referred to as anhydrous. You should recognize the OH, Example: CO would be carbon monoxide and CO. The rule said that for molecular compounds that only contained non-metals we use (# prefix) first compound + (# prefix) second compound, but in the quiz it wants carbon monoxide instead of monocarbon monoxide, and I'm just confused when the leading element gets the prefix, when it doesn't, and what rules there were surrounding that? Join a game Log in Sign up. How do you … To name covalent compounds, first memorize the prefixes that are used to indicate the number of atoms. In all cases, ionic compound naming gives the positively charged cation first, followed by the negatively charged anion. Naming Ionic Compounds with Polyatomic Ions. Name the nonmetal ion second. With covalent compounds, a charge of 2 is represented by the prefix di-, but carbon here has a charge of 3. View a full description and pricing on our web store. What is the name of the new compound? If the the formula does not fit the "invisible rule" then use ( ) to write a roman numeral to indicate the charge of the metal.

In a compound that contains iron and fluoride, the metal (iron) would go first. General rule. Rule 1. The process of naming ionic compounds with polyatomic ions is the same as naming binary ionic compounds. 45. 1. Ionic compound nomenclature or naming is based on the names of the component ions. PO4 has an oxygen removed from the compound. Dinitrogen Hexafluoride Between two NONMETALS Sharing of Electrons Change endings of the last element to -ide Are named by Greek prefixes: (Goes in the front of name) Naming Rules for Organic Compounds The names of organic molecules are divided into three parts; 1. the ‘root’ name, indicative of the number of carbon atoms in the longest continuous chain, which includes the highest priority functional group. Use lower case letters for the compound name. Prefixes are used to denote the number of atoms. 48. Read on for another quiz question.
