The two purposes of the poster are
(a) to reinforce the knowledge and perspectives
offered in a standard chemistry course and (b)
to open the door to the particle physics concepts which explain how
atoms function as a whole. It is visually interesting, up to date, and
written so that any student can take away insight from the bullet-points
listed by each section.
of the poster shows the relative sizes of the
1s to 7s-orbitals of group I elements, with a speck-sized nucleus
in the lower left corner.
The composition of the nucleons (protons,
neutrons) is the central illustration of the chart, with the
up- and down-quarks denoted, along with their “colors”
and connections through gluon exchange.
This is explained clearly in the text.
The text is written at a level that is understandable for first year
chemistry or physics students, with highlighted vocabulary to allow
students to easily locate familiar terms.
The particles are introduced with their
discoverers and dates (both theorized and identified), providing a clear
sense that the model of the atom is still being modified as new studies
