Physical Science Naming Compounds Worksheet

Physical Science Naming Compounds WorksheetNaming of compounds is a fundamental concept in the field of chemistry. It involves the assignment of a unique name to compounds based upon its composition. What is the title of a compound is a crucial indicator of its properties and the structure. There are different kinds of chemical substances, including organic compounds, covalent ones, and even binary compounds.

Naming Ionic Compounds

Ionic compounds are formed through electron transfer amongst atoms. They are made up of negatively charged cations and negatively charged anion. The rules of naming ionic compounds are as like this:

  1. The name of the an atom first, followed by what is the name for the anion.
  2. If the cation could have more than one charge be sure to identify the charge using Roman numbers enclosed in parentheses.
  3. For anion that is not a polyatomic ion, make use of the name for the anion.

Examples:

  • NaCl is known as sodium chloride.
  • FeCl3 is also known as iron(III) chloride.
  • Mg(NO3)2 is also known as magnesium-nitrate.

Naming Covalent Compounds

The formation of covalent compounds is caused by sharing electrons among atoms. They are made up of molecules composed comprising two or more atoms. The rules for naming covalent compounds are as they are:

  1. Note the name of first element in the formula.
  2. Write“Element 2” as the title in the formula, and change the end“-ide” to “-ide”.
  3. Use prefixes for the number of atoms in each element in the molecule. However, there is no need for“mono,” for example “mono-” for the first element.

Examples:

  • CO2 is also known as carbon dioxide.
  • N2O is named dinitrogen monoxide.
  • SF6 is named sulfur hexafluoride.

Naming Binary Compounds

Binary compounds are made of two components. The rules for names of binary compounds can be described as like:

  1. Name the first element of the formula.
  2. Enter“name” of second component in the formula, and change the end“-ide. “-ide”.

Examples:

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

Practice Exercises

To help reinforce learning to reinforce the learning, the worksheet will contain the practice of naming ionic components, covalent compounds, also known as binary compounds. These exercises will help students get a better understanding of the rules used to name chemical compounds.

Ionic Compound Naming Exercises:

  1. Na2S
  2. KBr
  3. CaF2
  4. Al2O3

Covalent Compound Naming Exercises:

  1. CO
  2. SO2
  3. N2O4
  4. H2O2

Binary Compound Naming Exercises:

  1. Cl2O7
  2. P2S5
  3. BrF3
  4. NO

If they can complete these assignments, students will be confident in understanding chemical compound names and be able to apply the rules to other chemical compounds.

Conclusion:

Naming compounds is an essential aspect of chemistry that requires a good understanding of the rules and guidelines for calling different kinds of compounds. In following the principles laid out in this worksheet and experimenting using the activities included, students are able to confidently identify ionic and covalent along with binary and covalent compounds. This is a must for being successful in chemistry. It provides the foundation for further studies in the area.
