In most cases, the “mono-“ prefix can be omitted, because it is implied when it is not present. Recall that a molecular formula shows the number of atoms of each element that a molecule contains. __The cation is always named first and the anion second. You must memorize them instead. They exchange charges and end up with opposite ones. Sodium cloride Na+ Cl-NaCl 2. Buy Online. Balance the charges (charges should equal out to zero, also known as a neutral charge). With covalent compounds, a charge of 2 is represented by the prefix di-, but carbon here has a charge of 3. {"smallUrl":"https:\/\/www.wikihow.com\/images\/thumb\/7\/7a\/Name-Chemical-Compounds-Step-1.jpg\/v4-460px-Name-Chemical-Compounds-Step-1.jpg","bigUrl":"\/images\/thumb\/7\/7a\/Name-Chemical-Compounds-Step-1.jpg\/aid1286499-v4-728px-Name-Chemical-Compounds-Step-1.jpg","smallWidth":460,"smallHeight":345,"bigWidth":"728","bigHeight":"546","licensing":"

\n<\/p><\/div>"}. Rules for Naming Molecular Compounds: Remove the ending of the second element, and add “ide” just like in ionic compounds. I cant solve any numericals in chemistry because I always get confused in solving the, "Really concise article, clarified questions I have had in class for weeks. To name chemical compounds, first determine whether the compound is ionic, polyatomic, or covalent. There are different types of ionic compounds, but the general rules in naming them … __The cation is always named first and the anion second. The cation is named first, followed by the anion. Thanks for A2A. The metal element always comes first in the name, and the nonmetal element comes second.
