Orbits and Orbitals KLM vs spdf. KLM and spdf??? KLM – old style lettering for the shells or orbits. K is closest to the nucleus, L is next, M (N,O,P.
Trick or Treat. #1 Which are the sublevels in an energy level of n = 2? a.s & f c.s, p, and d b.s & d d.s & p.
Z = proton number = atomic number N = neutron number A = mass number (Z+N) Atomic mass of nuclide = (rest mass – binding energy) relative to 1/12.
