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.

What is the electronic structure of Group One elements and how does it relate to their reactivity?

Describe the trend in softness of Group One metals as you move down the group.

How do the outer electrons of Group One metals affect their ability to react with water?

Explain why cesium is considered the most reactive metal in Group One.

What is the concept of shielding in relation to the reactivity of Group One metals?
