Group1 As An Example Of Groups In The Periodic Table

The video tutorial explains the properties and reactivity of Group One elements in the periodic table, including lithium, sodium, potassium, rubidium, cesium, and francium. These elements have one electron in their outer shell and are soft metals that become softer down the group. They are highly reactive, especially with air and water, and are stored in paraffin or inert gases. The reactivity increases down the group due to the ease of losing the outer electron, a concept explained by shielding, where inner electrons interfere with the nucleus's hold on the outer electron.
