Each group and period in the periodic table has its own cool features that make chemistry super interesting!

Groups (Columns):

1. Group 1 (Alkali Metals): These metals are really reactive, especially with water, and they are light in weight.
2. Group 2 (Alkaline Earth Metals): These are also reactive, but not as much as Group 1. They make basic compounds called oxides.
3. Group 17 (Halogens): These are non-metals that are very reactive. They can be found in different forms, like gases or liquids, at room temperature.
4. Group 18 (Noble Gases): These gases are not reactive and are stable because they have a complete set of electrons. They’re pretty chill!

Periods (Rows):

• When you move across a period, the properties change. You’ll find that metals are on the left side, while non-metals are on the right. As the atomic number goes up, you see changes in how reactive they are and how dense they are.

These unique traits make each group and period special! It’s important to understand them to learn more about chemistry.
