Question

What is the similarity in the electronic structure of lithium,sodium and potassium

Answer 1

all have 1 valence electron or there are 1 electron in last shell of these all element. these have valency 1 and they are alkali metal

Answer 2

"All the three elements, i.e. Lithium, Sodium and Potassium has a single electron that is on the outermost shell and the electronic configurations of

Lithium is 2, 1

Sodium is 2,8, 1

Potassium is 2, 8, 8, 1

Potassium will be reacting faster compared to the other three elements as its electron would be located in the farer distance and this would get easily attracted to the nucleus due to less force and will be losing with ease.
