Question

g Give the electron configurations for the following atoms. Do not use the noble gas notation. Write out the complete electron configuration. Example: Mg 1s22s22p63s2 Element Electron configuration Ne Li N S Sc

Answer 1

Answer:
`Ne:1s^22s^22p^6`

`Li:1s^22s^1`

`N:1s^22s^22p^3`

`S:1s^22s^22p^63s^23p^4`

`Sc:1s^22s^22p^63s^23p^64s^23d^1`

Step-by-step explanation:

Electronic configuration represents the total number of electrons that a neutral element contains. We add all the superscripts to know the number of electrons in an atom. The electrons are filled according to Afbau's rule in order of increasing energies.

The electronic configuration for given elements is as follows:

`Ne:10:1s^22s^22p^6`

`Li:3:1s^22s^1`

`N:7:1s^22s^22p^3`

`S:16:1s^22s^22p^63s^23p^4`

`Sc:21:1s^22s^22p^63s^23p^64s^23d^1`
