Answer:
How many electrons are there in the lithium ion?
The battery goes on and on and on.
Each element have an electron configuration in depending of the principle (Hund’s rule , etc).
So by their atomic number tend to indicate the number of protons that are equal in a number of electrons.
So the atomic number indicate the numbers of electrons.
Atoms have direct stability as such lithium tend to be located in group 1A and period 2.
Lithium have the atomic number of 3.
So naturally their protons/number of electrons are 3.
The electron configuration is (LI) 1s² 2s¹ or [He] 2s¹.
To archive stability as any noble gas element HE , Then the lithium will form an electron to form a Lithium ion which is Cation LI+.
So by it the lithium ion had 2 electrons.
