A shell includes all orbitals with
the same principal quantum number (n). In this figure the principal
quantum numbers are designated along the bottom (n = 1, n = 2, etc.) and the orbitals
contained within the shell are shown as individual, colored boxes.
The first shell (n=1)
contains only 1 orbital, represented by 1 yellow box. The second
shell (n=2) contains a
total of 4 orbitals, represented by 1 yellow box and 3 blue boxes.
Use the figure to...
