Ground type Pokemon can be paralyzed but eletric moves dont have effects on ground types.
And YES, flinging a light ball to a ground type Pokemon can paralyze the opponent and give 30 damage attack.
So I think it works. Hope it helps
Can holding the Light Ball (Pikachu's item) and using Fling paralyse a Ground-type Pokemon? The title pretty much has all the detail I want to know. Accepted Answer From: giratinaaltered 3 months ago Nope. Pretty much the same logic when you Fling a Toxic Orb to a Poison- or Steel-type or a Flame Orb to a Fire-type.

Edit: I am sorry I tested it in game and found that Light Ball can paralyse Ground type Pokemon. So I was incorrect and ShinyFire was correct.
