Day 6: Contents of the Atom then Research Time for Atomic Theory
Presentation
-Over Head "Contents of the Atom"
-Discuss prior knowledge, how each component contributes to chemical
properties or change as we know it, and solidly link the "stability" of
the proton to atomic number
-Library time to work on Atomic Theory Presentation |

Contents of the Atom
Begin by asking
the students what they know about the atom, what is it made of? On the
white board, construct a model using the knowledge they retained from
grade 10 science.
Students copy an overhead outlining the contents and
characteristics of the atom from the smallest to largest part. As we
work through the overhead, the stability of each is discussed. Protons
change in nuclear reactions, neutrons lost leads to radiation, and
electrons are frequently lost, gained, or shared; the basis of all
chemical change. Start to enforce the understanding that the number of
protons identifies the element and the element identifies the number of
protons, this relationship was made since protons are vary stable and
only change during nuclear reactions.
