Activity 6: The
characteristics of the atom the atomic and the mass numbers
Each type of atom represents a certain chemical
element. This means that there must be something in the atom that
differentiates it from all other atoms. Look the following image:
Activity 7: Build an atom
Go to the following link: https://phet.colorado.edu/sims/html/build-an-atom/latest/build-an-atom_en.html and click Play,
then select Atom
1)
Use
the tools to build any three, different types of atoms and fill in the
information about them below:
2)
Which
subatomic particle is the boss of the atom? What evidence does the simulator give
you for this?

3)
Create
a Hydrogen (H) atom (1 proton, 1 neutron, 1 electron). Follow the directions,
observe what happens and complete the table below. (You need to RESET back to your original Hydrogen (H) atom (1
proton, 1 neutron, 1 electron) after you make each change!)
4) Based
on what you’ve observed, which two
particles appear to determine the mass of the overall atom? Which
particle doesn’t seem to have a measurable impact on the mass? Explain
why you think this is!

5)
Based
on what you’ve observed, summarize the relationship between
how protons, neutrons and electrons affect the overall charge of an atom.

6)
If
you’ve been paying attention, you should have noticed that the term Ion appears from time to time.
Experiment with the simulator and list the two ways you can create a positive
ion and a negative ion:
a) Two
ways to create a positive ion:
__________________________________________________________________________
b)
Two
ways to create a negative ion:
__________________________________________________________________________
c)
What
do you think the term ion means?
