In science, we learned about atoms and molecules. We made models
of atoms of certain elements. This is how we made our models.
First, we were given an element. Then we had to figure how many protons
neutrons and electrons the element had. Next we had to do our sloppy
copy and in it we had to determine how many electrons had to go on each
shell or orbit.
These are the rules of how many electrons are allowed on each shell. On
the first shell you can only put 2 electrons, the second shell 8 are allowed,
third shell 18, fourth shell 32, fifth shell 50, sixth shell 72, seventh
shell 78, etc....
After determining how many shells we needed we had to write letters to
show the amount of protons, neutrons and electrons we used. We then
showed to are teacher and took our final copy we then wrote our sloppy
copy over replacing the letters with peas and lentils. The protons were
represented by green peas, the neutrons were represented by yellow peas,
and the electrons were represented by brown lentils. Before we replaced
the letters we outlined the shell the nucleus and the key words in black
marker. We put the name of the element on the top and the symbol
that represents your element next to it. After that we put our finished
copy on a white piece of cardboard and waited for the glue to dry. Lastly,
we scanned it and put it on this web page.
