The rules for writing the chemical formulas of covalent compounds must include the use of prefixes, naming the first non-metal and replacing the end name of the second non-metal with "ide".
A covalent compound is a type of compound that contains covalent bond --the atoms share pair of electrons.
There are basic rules for writing the chemical formulas of covalent compounds, these rules include the following;
Use the prefixes such as mono (1), di (2), tri (3), to indicate the number of that particular element in the given compound.
<em>Start </em>by naming the firstnon-metal present in the compound, which is found far left on the periodic table by its elemental name.
<em>Followed by</em> naming the second non-metal by replacing the end of its elemental name with an "ide".
