Q
Reasons for Reactivity Increasing going down group 1:
A
- There is more distance between the nucleus and outer shell
- Atomic radii increases
AND - More shells are separating the nucleus and outer shell
- Shell shielding increases
- Electrostatic Attraction between the nucleus and valence electrons decrease
- Outer shell electron is less strongly held as the effect of the nucleus is weaker
- Consequently it requires less energy to remove a valence electron
