6 Short cut = Core notation
Core notation takes the electron configuration of the last noble gas and adds the additional electrons, in their perspective orbitals, to show the same electron configuration of the element

7 Group 1 Group 6 O [He]2s22p4 S [Ne]3s23p4 Se [Ar]4s23d104p4 Te [Kr]5s24d105p4 Po [Xe]6s24f145d106p4 H 1S1 Li [He]2s1 Na [Ne]3s1 K [Ar]4s1 Rb [Kr]5s1 Cs [Xe]6s1 Fr [Rn]7s1

8 Exceptions Cr and Cu Cr (d4) borrows 1 electron from s-orbital
Cr ([Ar] 4s1 3d5) half filled d orbital is very stable Cu fully filled d orbital Cu ([Ar] 4s1 3d10) filled d orbital is very stable

9 Electron configuration for ions
Negative ion – add electrons to the last unfilled subshell Positive ion - electrons in outermost shell are removed first Remove p before s before d- electrons

10 Classwork: p 156 – 158 #
