Answer explanation

Fun Fact: This is a lithium ion, responsible for every battery powered device you own, from your phone, to your chromebook, to the electric vehicles of today! Next year, in chemistry, you will learn what it means for an atom to be an ion.

Not so fun fact: We are running out of Lithium. The UK wants all its vehicles to be electric by 2030. To produce enough lithium to meet that demand, EVERY lithium mine in the entire world would have to dedicate its production to just UK electric vehicles, and there are many more countries that have made a similar commitment, AND, as mentioned we need lithium for much more than just cars.
