Compound Naming Worksheet Answers – Naming compounds is an important idea in the field of chemistry. It is about assigning a specific name to an chemical compound, based on its composition. In addition, the name assigned to the compound provides important information about its properties and the structure. There are different kinds of chemical compound, including those with ionic properties, covalent compound, as well as binary compound.
Naming Ionic Compounds
Ionic compounds arise from the transfer of electrons between atoms. They consist mostly of positively charged electrons and negatively charged anion. The rules for naming Ionic compounds are as the following:
- Write the name of cation first, followed by the name of the anion.
- If the cation is charged with more than one charge Indicate the charge with Roman numerals in brackets.
- For anion that is not a polyatomic ion refer to the name of ion.
Examples:
- NaCl is known as sodium chloride.
- FeCl3 is named iron(III) chloride.
- Mg(NO3)2 is also known as magnesium oxide.
Naming Covalent Compounds
Covalent compounds arise from sharing electrons among atoms. They are made up of molecules composed up of two or more atoms. The guidelines for naming compounds that are covalent are as in the following order:
- Note the name of first element in the formula.
- Write“ide” in place of “ide” of the formula, and change the ending“-ide” to “-ide”.
- Prefixes should be used to indicate number of elements in each element in the molecule. The exception is“mono-,” the particular prefix “mono-” for the first element.
Examples:
- CO2 is a carbon dioxide derived name.
- N2O is named dinitrogen monoxide.
- The term SF6 stands for sulfur hexafluoride.
Naming Binary Compounds
Binary compounds are the ones made up of two elements. The rules for the name of binary compounds are they are:
- Enter the name of the first element in the formula.
- Write your name for the element of the formula, changing the end“-ide. “-ide”.
Examples:
- The chemical name for HCl is hydrogen chloride.
- CO is a synonym for carbon monoxide.
- CaO is named calcium oxide.
