What happens to metallic activity as you move down Group 1 of the periodic table?
What happens to metallic activity as you move down Group 1 of the periodic table?
Metallic activity tends to increase.
Explain why there is an increase in metallic activity down Group 1.
Explain why there is an increase in metallic activity down Group 1.
The increase is because the outer electrons are further from the nucleus, making them easier to lose.
How does the atomic structure of Group 1 elements influence metallic activity?
How does the atomic structure of Group 1 elements influence metallic activity?
Group 1 elements have a single electron in their outer shell, which is lost easily, increasing metallic activity.
In terms of reactivity, how do the metals at the top of Group 1 compare to those at the bottom?

Study Notes
Metallic Activity Down Group 1
- Metallic activity increases as you move down Group 1.
- This is because the atoms become larger and have more electron shells.
- This increases the distance between the nucleus and the valence electron.
- The valence electron is less tightly held by the nucleus and is easier to remove.
- Therefore, the ionization energy decreases down Group 1, making the elements more reactive.
Atomic Structure and Metallic Activity
- Group 1 elements have one valence electron.
- This electron is easily lost, giving the elements a +1 charge.
- This makes them highly reactive, especially with non-metals.
Reactivity of Alkali Metals
- The metals at the top of Group 1 are less reactive than those at the bottom.
- Lithium (Li) is the least reactive, while francium (Fr) is the most reactive.
- This is due to the increasing distance between the nucleus and the valence electron, which makes it easier for the valence electron to be lost.
Ionization Energy and Metallic Activity
- Ionization energy is the energy required to remove one electron from an atom in its gaseous state.
- As you move down Group 1, the ionization energy decreases.
- This means it becomes easier for the elements to lose their valence electron.
- The lower the ionization energy, the higher the metallic activity.
