Task #3. Drawing the atomle structure of atoms. 1. On the following page, draw the atomic structure of the elements using the follow
Ing directions and example,
2. Use the planetary model discussed in class.
3. First, use the atomic number and mass number of the element to determine the
number of protons and neutrons of the atom.
4. Next, draw a small circle to represent the nucleus (to match the example on the
next page)
5. Inside this circle, write the number of protons and the number of neutrons that
the atom has
6. Determine the number of electrons of the atom,
7. Determine the number of shells of the atom. For simplicity, we will assume that the
first shell can hold up to 2 electrons, the second shell can hold up to 8 electrons,
and, for the main group elements used in this activity, the third shell can hold up
to 8 electrons. (Note that the transition elements can hold up to 18 electrons in
their third shell, but we will not be dealing with those elements in this activity)
8.
Draw circles around the nucleus to represent the shells.
9. Make large dots on each circle to represent the number of electrons in that shell,
