Question

write the electronic configuration of
alkali metal group​

Answer 1

Answer:

The elements in Group 1 (lithium, sodium, potassium, rubidium, cesium, and francium) are called the alkali metals. ... For example, the electron configuration of lithium (Li), the alkali metal of Period 2, is 1s22s1. This single valence electron is what gives the alkali metals their extreme reactivity.
