Part 2: Report and Reflection
Purpose: Describe in complete sentences and in your own words, the purpose of
this experiment.
the purpose of this experiment was to be able to identify the different periods, groups,
and family types of the periodic table. it showed the elements categorized as elements
as metals or nonmetals. after learning about the different areas on the periodic table, I
will now be able to identify what type of element it is based on its location.
Observations: Record three observations from the simulation.
1. protons and neutrons make up the atomic mass.
mass number = protons + neutrons
atomic number represents the number of protons and is fixed for every element
2. elements in the same period have the same number of electron shells and tend to
have similar properties. whereas elements in the same group have the same electron
configuration in their valence shell.
3. all elements that have eight electrons in their valence shell complete an octet and are
known as noble gases.
