## Homework Statement

Here's the pic of the problem and my work

## 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?
