1. The problem statement, all variables and given/known data Here's the pic of the problem and my work 3. The attempt at a solution I'm not sure how i'm suppose to calculate the energy change? Did i do it correctly in the picture? For number 9, I just added IE1 and IE2 and subtracted EA1 to get a total of 3200.3. This means that the atom would be absorbing energy right? For number 10, like wise, i just added and subtracted for the IEs and EAs and got 1501 and it also means that it's absorbed Honestly not quite sure what i'm doing . Can someone explain these 2 problems?
