Starting Materials
The Key
Hydrogen
1 electron, 1 proton, 0 neutrons
Helium
2 electrons, 2 protons, 2 neutrons
Lithium
3 electrons, 3 protons, 3 neutrons
Questions:
1. What
is the atomic number for each of your models?
Hydrogen:
1
Helium: 2
Lithium:
3
What is
the atomic mass number for each of your models?
Hydrogen: 1.008
Helium: 4.002602
Lithium: 6.94
3. In
your models, which two subatomic particles are equal in number?
Protons
and Neutrons were the same in everyone.
4. How
would you make an isotope for one of your models? What would change with the
model?
I could
have and should have changed my models, I wish I would have used darker
markers, to make it more visible. I also would have changed the number of
neutrons to make an isotope for one of the models. If the neutrons get changed,
the atomic mass number would also change, however the atomic number would have
remained the same. If I would have done this I believe I could have been more
credible.
5.
Considering the overall volume of your element models, what makes up most of
the volume of an atom?
After
observing my models, I noticed that the central nucleus makes up the most
volume, by protons and neutrons along with the surrounding electrons.
6. For
one of your models, show with another image what happens when energy excites an
electron.
I
couldn't think of a way to present the information of an excited electron all
in on picture so I just found and posted one from online.
7. Once
the electron is excited, what do we typically observe when the electron returns
to the ground-state?
8. Why are
some elements different colors when they are excited? Hint: when electrons are
excited (by something like heat from an explosive) they move up to another
orbital and when they fall back they release the energy in the form of light.
9. With
the Fourth of July coming up quickly, explain how the colors of fireworks arise.
10.
Explain the overall organizational structure of the periodic table.
