Writing and naming ionic compounds

They would love to have eight, so they tend to be really good at grabbing electrons. So this we would refer to as Chloride. Usually, the positively charged portion consists of metal cations and the negatively charged portion is an anion or polyatomic ion. For example, a compound containing calcium always starts with "calcium.

This compound is therefore, copper II nitrate. Another type of bonding occurs when atoms with a net charge are electrostatically attracted to atoms or molecules with the opposite charge.

ionic compound formula

Positive to positive and negative to negative ionic bonds do not occur. K is the symbol for potassium.

Naming ionic compounds examples

You have a positively charged potassium and you have a negatively charged chlorine, which we would call a chloride. Let me write that down. Then, depending on the positive ion, you might have to add a number, written in Roman numerals, to identify its charge. The name of the compound is therefore iron II oxide. Now things in group one here, one way to think about is their outermost shell has one electron in it. So this we would refer to as Chloride. In this first column, this first column is often known as alkali metals. Ions can be single atoms, as the sodium and chlorine in common table salt sodium chloride , or more complex groups such as the carbonate in calcium carbonate. The net charge of an ionic compound must be zero. When identifying the compound, the name of the cation always goes first. The name of the ionic compound indicates the charge of the cation in brackets after its name. When the anion is a polyatomic ion, use the name of the ion unchanged. Write the name of the cation, and then write the name of the anion, changing the ending to "-ide" if it's a single element and leaving it as it is if it's a polyatomic ion. This compound is therefore, copper II nitrate.

In the next few videos I'll do many, many more examples of this and ones that will be a little bit more complicated. And so let's say we're dealing with chlorine, and chlorine is able to ionize.

The name of the ionic compound indicates the charge of the cation in brackets after its name. So things in group, in the halides, which is this column right over here. Convert between the chemical formula of an ionic compound and its name Key Points Most cations and anions can combine to form neutral, solid compounds that are usually known as salts.
