how do i write electronic configuration of an elctron in its excited state?

Question

can u plz show with examples how the electronic configuration of an element changes when its in the 1st excited state,2nd excited state...?

Answer 1

i believe "excited" state simply refers to an element operating at a higher energy state than normal (extra electron(s))

For example:
Lithium - generally 1s(^2)2s(^1)

Excited Lithium - 1s(^2)2s(^2) = 1st excited state

Answer 2

To write the electron configuration for an excited state of an atom, promote one or more of the electrons to a higher energy orbital.

For example, the ground state electron configuration of He is: 1s^2.

A possible excited state would be 1s^1 2s^1. One of the electrons has been "bumped up" from the 1s orbital to the 2s orbital.
