Ionic Compounds by Summer

This week in chemistry we were working with ionic compounds and how to identify elements with cations and anions. Ionic compound is a chemical compound in which ions are held together in a structure by electrostatic forces. They call it ionic bonding. This compound is neutral overall but consists of positively charges ions and negatively charged ions, which are called Cations and Anions. Ionic compounds can only consist of a metal and a nonmetal. We also learned how to say the proper names of ionic substances and that we have to use the actual name of the elements instead of the symbols.


In this picture it shows the cations, anions, and the compound it forms. In order to find what compound it makes you have to balance out the electrons. When you are balancing the electrons, you need to know what the charge is.

You also need to know the traditional name of the compound. YOu figure them out by knowing whether or not they form one or two ions. For example, NaCl is Sodium Chloride, since it only has one ion. An example of metals that form multiple ions are CuO, Cupric Oxide. It only matters on how many Ions it can form.

Questions;

What are Anions?
What are Cations?
