Answer:

See explanation

Explanation:

To find out the electronic structure of each element, you must know the number of electrons it contains.

If you find that out(the number of electrons in the neutral atom of an element is the same as its atomic number). Then you arrange those electrons in such a way that the first shell has only two electrons and subsequent shells have eight electrons.

Look up the groups to which the elements belong in the periodic table All the elements are in group 1 so the last shell must have only one electron.
