Formulas And Naming Of Polyatomic Compounds Worksheet Answer Key – Naming compounds is an important idea in the field of chemistry. It is the process of assigning a distinct name to one chemical substance based on its composition. The name of a compound provides crucial information about its properties and structures. There are several kinds of chemical compounds. They include the ionic compound, covalent compounds, the binary type of compounds.
Naming Ionic Compounds
Ionic compounds are created by moving electrons around atoms. They consist in positively charged caustics as well as negatively charged anion. The rules to name ionic compounds are as in the following order:
- Write the name and the catalytic cation in the first place, then your name and the name of the anion.
- If the cation may have more than one possible charge identify the charge by using Roman numerals in parentheses.
- If it is a polyatomic Ion, identify the Ion.
Examples:
- NaCl is also known as sodium cyanide.
- FeCl3 is named iron(III) chloride.
- Mg(NO3)2 is known as magnesium Nitrate.
Naming Covalent Compounds
Compounds that are covalent are formed through sharing electrons among atoms. They consist of molecules made comprising 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“name” of second component in the formula, changing the end to “-ide”.
- Use prefixes to indicate the amount of atoms that make up every element of the molecular structure, except for using the suffix “mono-” for the first element.
Examples:
- CO2 is a carbon dioxide derived name.
- N2O is named dinitrogen monoxide.
- SHF6 is the name given to sulfur hexafluoride.
Naming Binary Compounds
Binary compounds are substances made up of two elements. The rules for the naming of binary compounds are as these:
- Then write the name of first element in the formula.
- Enter the name of the second element in the formula, changing the ending in the form of “-ide”.
Examples:
- Hydrogen chloride is the name given to it.
- CO is known as carbon monoxide.
- Calcium oxide is also known as.
Practice Exercises
To reinforce the learning and reinforce learning, the worksheet includes drills for naming Ionic molecules, covalent compound and binary compounds. These exercises can help students improve their understanding of the rules of naming chemical compounds.
Ionic Compound Naming Exercises:
- Na2S
- KBr
- CaF2
- Al2O3
Covalent Compound Naming Exercises:
- CO
- SO2
