I forget how to determine the charge of an element based on its electron configurationI know it has to do with how electrons fill outer orbitals, but I have seen too many conflicting 'methods' and now i am confusedFor example, what is the predicted charge on a molecule that has the electron configuration of (1s2)(2s2)(2p6)(3s2) The answer key say +2, but I don't see itHow would you figure it out if you were given the electron configuration for aluminum or fluoride?Thanks
