Electron Configuration Chart of All Elements (Full Chart

The electron configuration describes the distribution of electrons in the shell of an atom at various energy states. This is described by the occupied sub-shells. The shell number is followed by the letter of the sub-shell, with the number of electrons in the shell indicated by a superscript number So, if we were to add all the electrons from the above electron configuration, 2+2+6+2+6+2+10+6+2+10+6+2+14+10+3=83. Remember, the f orbital has to included before the d orbital because bismuth is after the lanthanide series. Another way to look at how the electrons are arranged in bismuth is in orbitals. These are the numbers that students' in. The third major category of elements arises when the distinguishing electron occupies an f subshell. The first example occurs in the case of the lanthanoids (elements having atomic numbers between 57 and 71).The lanthanoids have the general electron configuration [Kr]4d 10 4f i 5s 2 5p 6 5d 0 or 1 6s 2. where i is a number between 0 and 14.
