Answer 2

Electronic Structure of Alkali Metals

The electronic structure of alkali metals can be represented as 2e,1e.

This means that each alkali metal atom has 2 electrons in its outermost shell and 1 electron in the next inner shell.

This information is supported by the electronic configuration of alkali metals, where the outermost shell contains 1 electron, and the next inner shell contains 2 electrons.

Therefore, the correct answer to the given question is 2e,1e.
