1. The problem statement, all variables and given/known data Calculate the energy of the electron in the ground state of triple ionized beryllium, which has an atomic number Z = 4. 2. Relevant equations -Z2 (13.6) N2 3. The attempt at a solution Z=4 as given and it is tripled so our N=3. We throw our numbers in there and we should have -(16)(13.6). Take that product and divide it by 9. I got an answer of -24.18, but I am incorrect. Unfortunately, I do not have my textbook with me right now so I might have the equation all wrong. I would really appreciate it if someone could give me a hint or a good website to learn from. THANK YOU!!!
