The f orbitals are buried even more deeply, and adjacent
inner transition metals show almost no difference in chemical behavior.
The electronic configuration of any atom, and the structure of the
periodic table, both are consequences of the energy-level diagram
obtained from spectroscopy and wave mechanics. The idealized electron
arrangement of any atom can be worked out from its place in the
Tin (Sn) is found in the p
column of the representative elements, in row five of the periodic
table. What is its electronic structure?
Building up the atom, following the orbital-filling diagram available
on page 12, until 5p
is reached, you can see that the electronic structure of the tin
atom must be
This can be simplified by using the symbol [Kr] to represent the
inner core of electrons of the noble gas krypton:
