Ionic Bonds Practice

In each atom on the periodic table, you can fine the number of ​ (a)   by looking at the atomic number. You will also find a one/two letter code called a ​ (b)   that helps you identify it. The number at the bottom with all the decimal points is the ​ (c)   .

• protons and electrons
• chemical symbol
• atomic weight
