What is an ionic compound? An ionic compound is where two elements transfer electrons, usually a metal and a nonmetal.
Now let's get started!
Example: Potassium (+) and Sulfur (-)
1. When naming compounds, you have a positive (+) and a negative (-). When you write the name down, the positive always
2. Write the name of the positive down first.
3. Then write the negative down, adding -ide at the end of the root.
There! You did it!
Naming covalent compounds is a bit trickier than ionic compounds. First of all, what is a covalent compound? A
covalent compound is a compound where the elements share electrons rather than transfer them. A covalent compound is made
up of two nonmetals.
* If there is more than one element in the molecule, you must add prefixes to the name of the element depending on the
number of elements. Look:
So let's say you have the formula C6 Cl3
You would do the same thing as you did with ionic compunds: put the positive first, and add -ide to the end of the negative
one. If there is no charge, start from the left, putting the element farthest left on the periodic table first.
But here's the extra part: adding the prefix.
Since there are 6 carbons you would use the 'hexa' prefix...
Since there are 3 chlorides, you would use the 'tri' prefix...
That's all there is too it!
