What is the electron configuration of the second excited state of lithium?

The electronic configuration of second excited state for lithium atom is

See the step by step solution

Step by Step Solution

Step 1. Given information

The number of possible electrons in orbital (or shell) is 2 ,

the number of possible electrons in orbital (or shell) is 6 ,

the number of possible electrons in orbital (or shell) is 10,

and the number of possible electrons in orbital (or shell) is 14 .

Step 2. Explanation

We must determine the electron configuration of lithium's second exited state.

In the ground state, the lithium atom (Z= 3) contains two electrons in the 1s shell and one electron in the 2s shell.

For the first excited state of lithium, the electron configuration is:

As a result, the electron configuration for lithium's second excited state is:
