The information is present in a clear
way, along with the color scheme which highlights group similarities
and s-, p-, d- and f-blocks of elements. The color darkens as the atomic
number goes up in a period to indicate an increasing electron count.
The groups have identical colors to thereby show behavioral (and valence)
similarities. Further, the table shows the suborbital level that is
being filled (5p beside Indium) reinforcing students' understanding
of electron configurations.
