Question

How do you write an excited electron configuration for sodium?

Answer 1

Before we realize how to compose the electronic arrangement, it is vital to know the idea of shell, subshell, and nuclear orbital.
The energized state electron design shows when an electron is energized and bounces into a higher orbital. For instance, sodium in its energized state would have an electron design of $1{s^2}2{s^2}2{p^6}3{p^1}$ , contrasted and its ground condition of $1{s^2}2{s^2}2{p^6}3{s^1}$

Complete step by step answer:
The electronic arrangement of sodium atom is $1{s^2}2{s^2}2{p^6}3{s^1}$ Now in the event that we eliminate one electron from its valence shell the it's design will be $1{s^2}2{s^2}2{p^6}$
The energized state electron setup of a molecule shows the advancement of a valence electron to a higher energy state.
An electron arrangement addressing a molecule in the energized state will show a valence electron elevated to a higher energy level.
The ground state electron arrangement of sodium is $1{s^2}2{s^2}2{p^6}3{s^1}.$
In its energized express, the valence electron during the $\;3s$ sublevel is elevated to the $3p$ sublevel, giving the electron arrangement as $1{s^2}2{s^2}2{p^6}3{p^1}.$
This is a truly unsteady condition and the energized electron will drop down to the $\;3s$ sublevel, delivering the very measure of energy that was consumed, and creating a trademark shade of light, for this situation yellow.

Note: The ground state in an atom is when electrons are in the least conceivable energy level. In this express, the electrons have the least expected energy.
Then again, over the ground states are "energized states". These are states by higher energy than the one and only of the ground state. On the off chance that you shoot the atom with a photon, at that point the photon might be consumed, so the electrons of the particle will bounce starting from the earliest stage to an energized express (the contrast between the two energies of the last and beginning state is the energy of the photon that got retained). In an energized state, not all electrons are in the most reduced conceivable energy levels
A simple method to decide whether the electron is in the energized state is to contrast it with its ground state. On the off chance that you see electrons have been "moved" to a higher orbital prior to filling the lower orbital, at that point that iota is in an energized state.
