Alkali Metals and Their Properties

The video tutorial explores Group 1 elements on the periodic table, known as alkali metals, focusing on sodium. It explains the unique properties of alkali metals, including their single valence electron and tendency to form positive ions. The video also discusses why hydrogen, despite being in Group 1, is not considered an alkali metal. The tutorial concludes with a summary of the bonding behavior and ionic charge of alkali metals.

Where is sodium located on the periodic table?

• Group 2
