15. a- if an Lithium (atomic number 3) atom has a -2 charge, how many electrons does it have? - Why do you do it this way? - Is this an anion or a cation? d- Why? A- B- C- D- PLEASE HELP THANK YOU :)
Lithium will normally have 3 electrons and be neutral. If it has a -2 charge that means it has an extra 2 electrons making it a total of 5 electrons. It would be an “anion” and it would be attracted to the Anode which is positive.
