I don't understand it. I was absent the day it was introduced so I'm behind. I'm trying to learn from google but I cant figure it out. I thought I understood but I guess not. I picked a random element off the periodic table. Gold. I know thats sub level d row 5 column 11 So I thought it was just 5D11 I looked up the electron configuration for it and I got [Xe] 4f14 5d10 6s1 Any guidance? Because I'm clearly lost.
