Ineed completing this chart. i need to know how to get the charge of an element, the actual number of e- which i believe is beta, and the number of e- in a neutral atom. i also need to know what to do when there is a charge next to the element, are there different steps or the same? i need either steps or answers or both would be even more amazing i’m freaking out it is due soon !
