How can I tell, with an electronic configuration, if an element is in ground or exited state? Also, how can I determine what element it is if it uses a noble gas shortcut? I assume I find the noble gas in brackets, count the atomic number, add it to the elec config outside of the brackets, and that atomic number is what element it is? Or is it more complicated? My teacher said something about excited state being 'not normal', he didn't elaborate.
