“What are some of the special properties of the first group of elements on the periodic table?”

As a child, you may have looked up at the periodic table, saw that it was organized column by column, and asked why Chemists decided to construct it in that matter? Well, it turns out that each of the columns have been arranged together because they share many qualities with one another! So let’s begin with the first group, the Alkali metals. The alkali metals are the metals that sit on the far left of the periodic table. These elements include  lithium (Li), sodium (Na), potassium (k),cesium (cs), and francium (Fr) , and they all share kindred characteristics. First of all, they have only one valence electron in their outer shell, which makes them highly reactive with other elements. Second of all, when they do react, they usually turn into a positive cation.
