Glossary of chemical formulae

In this lesson we will learn how to write and interpret chemical formulas for elements and compounds. Lowercase or capital letter? It makes a big difference in chemistry! Sometimes the same type of atom can appear in more than one place in a molecular formula. Search for:.

Names and Symbols for Elements and Compounds. Learning Objective In this lesson we will learn how to write and interpret chemical formulas for elements and compounds. Learning Outcomes By the end of this lesson you will be able to: Write chemical symbols for elements.

Write chemical formulas for compounds. Identify the number of each type of atom in a molecule based on its chemical formula. These chemical symbols and formulas provide a quick and universal way of identifying pure substances in chemistry.

Symbols for Elements Each type of atom or element can be represented by a unique chemical symbol consisting of one or two letters. The first letter is written as a capital and the second letter, if there is one, is written in lowercase. Chemical symbols are abbreviations for the name of the element. This is quite similar to the English name. This is very different to the English name.

For example, try learning the names and symbols of the first 20 elements, as you will encounter these a lot in chemistry. They are listed in the following table. Commonly encountered metal elements outside of the first 20 are shown in the following table. Commonly encountered non-metal elements outside of the first 20 are shown in the following table. Formulas for Compounds Each type of molecule or compound can also be represented by a chemical formula.

The formula for a compound represents the number of each type of atom in its molecules or subunits. Chemical formulas consist of two parts: Chemical symbols of each type of atom. Numbers subscripts indicating how many of each atom is in a molecule or subunit if there is more than one.

Example 1 Water can be represented by the chemical formula H 2 O. The symbols H and O show that a water molecule is made up of hydrogen atoms and oxygen atoms. We could also say that water is formed from the elements hydrogen and oxygen. The subscript 2 after the H indicates there are two hydrogen atoms in a water molecule. No subscript after the O indicates there is one oxygen atom in a water molecule.

Example 2 Calcium hydroxide can be represented by the chemical formula Ca OH 2. The symbols Ca, O and H show that calcium hydroxide is composed of calcium, oxygen and hydrogen atoms. We could also say that calcium hydroxide is formed from the elements calcium, oxygen and hydrogen. No subscript after the Ca indicates there is one calcium atom in a calcium hydroxide molecule.

The subscript 2 indicates there is two of everything inside the brackets. Therefore, there are two oxygen atoms and two hydrogen atoms in a calcium hydroxide molecule. Sometimes the name of a compound can give a clue its formula. As with elements, it can be useful to memorise the names and formulas of common compounds.

Some compounds that you will encounter regularly in junior chemistry are shown in the following table. Some Things to Remember Many students get confused when writing the symbols for elements that exist as molecules, such as hydrogen, oxygen and chlorine. The correct symbol depends on whether you are writing it to represent the atom or the element the actual substance , which is made up of molecules. For example, the symbol for an oxygen atom is O, but the symbol for the element oxygen oxygen gas is O 2.

Remember that symbols for elements consist of only one capital letter. For example, there is a big difference between Co and CO. One is a metal element and one is a compound formed from two non-metal elements. By remembering this, you can also quickly determine if a substance is an element or a compound by checking if it contains one or more than one capital letter in its formula.

When counting up the total number of a type of atom in a compound, check if the element symbol is present more than once.

It is written like this to reflect the structure of the molecule. Summary Each type of atom or element can be represented by a unique chemical symbol consisting of one or two letters. The first letter is a capital and the second letter, if there is one, is lowercase. Each type of molecule or compound can be represented by a chemical formula. The formula represents the number of each type of atom in a molecule. It is therefore a combination of the symbols for the different atoms and numbers subscripts indicating how many of each atom is in a molecule.
