Predict the charge of the ion formed by each element. a. Mg

Video transcript

Hey everyone in this example, we need to identify the charge of barium when it becomes an ion. We want to recall that when something becomes an ion it's going to gain an electrical charge. And so right now, barium alone is just a neutral element. However, when we find barium on the periodic table, we'll see that it's in group to A. And we want to recall That Adam's in group two A. Are known to form a two plus cat eye on so acadian we recall is a positively charged ion. And so what we would form when barry in becomes an ion is the B. A. Two plus cat ion. And so this means that our berry um is missing two electrons that were likely pulled away from another atom that has a stronger electron affinity and pulled those two electrons from our barium atom forming our eye on here or cat eye on here. And so to complete this example, our charge of barium when it becomes an ion is B. A. Two plus. If you have any questions, please leave them down below and I will see everyone in the next practice video
