Answer: The configuration of lithium element is [tex]1s^22s^12p^03s^03p^04s^03d^04p^05s^0[/tex]
Explanation:
Electronic configuration is defined as the representation of electrons around the nucleus of an atom.
Number of electrons in an atom is determined by the atomic number of that atom.
We are given:
Atomic number = 3
The element having atomic number '3' is lithium
The electronic configuration of lithium element is [tex]1s^22s^1[/tex]
Hence, the configuration of lithium element is [tex]1s^22s^12p^03s^03p^04s^03d^04p^05s^0[/tex]
