Chemical Dry Lab Naming Compounds And Writing Formulas Worksheet

Chemical Dry Lab Naming Compounds And Writing Formulas Worksheet – Naming compounds is a fundamental idea in chemical science. It is the process of assigning a distinct name to each chemical compound according to its composition. An individual’s name on a compound gives important information about its properties and its structure. There are a variety of chemical compounds, such as Ionic compounds, covalent substances, and binary compounds.

Naming Ionic Compounds

Ionic compounds arise from an exchange of electrons among atoms. They consist in positively charged caustics and negatively charged anions. The rules of naming ionic compounds are as the following:

1. Write the name of the catalytic cation in the first place, then what is the name for the anion.
2. If the cation could have multiple possible charges make sure to indicate the charge with Roman numbers in parentheses.
3. If an anion’s structure is polyatomic Ion, identify the anion.

Examples:

• NaCl is a common name for sodium chloride.
• FeCl3 is named iron(III) chloride.
• Mg(NO3)2 is known under the name magnesium nitrate.

Naming Covalent Compounds

Covalent compounds are formed by sharing electrons among atoms. They consist of molecules that are made by two or many atoms. The rules for naming covalent compounds are as they are:

1. Inscribe the name and the first element in the formula.
2. Enter in the first element’s name in the formula, and change the ending to “-ide”.
3. Utilize prefixes to represent the quantity of atoms contained in each element in the molecule. The exception is“mono-” for the first element “mono-” for the first element.

Examples:

• Carbon dioxide is the name of CO2.
• N2O is named dinitrogen monoxide.
• SHF6 is the name given to sulfur hexafluoride.

Naming Binary Compounds

Binary compounds are the ones made by two elements. The rules for choosing the proper name for binary compounds is as they are:

1. Name the first element in the formula.
2. Write“Name” for second element in the formula, and change the ending to “-ide”.

Examples:

• The name HCl refers to hydrogen chloride.
• CO is the name given to carbon monoxide.
• Calcium oxide is known as CaO.
