Follow these directions in the simulation:
1. Select the "Atom" activity
2. Click and drag one proton (red), one neutron (gray), and one electron (blue) onto the atom in the center of the screen.

Answer the following questions about the simulation
Where did the proton (red) end up in the atom?
Follw these directions in the simulation:
Select the "Atom" activity.
Click and drag one proton (red) and one neutron (gray) onto the atom in the center of the screen.
Notice that the message above and right of the atom reads "+ ion". Click and drag electons (blue) onto the atom until the message changes to "Neutral Atom".
Answer the questions below by stating how many electrons you would need to make a "neutral atom" and the element name.
IMPORTANT: Please format your answer as such "# of electrons, name of element"
Example: 2, Helium
Number of electrons with 1 proton and 1 neutron?
Number of electrons with 1 proton and 0 neutron?
Number of electrons with 2 proton and 1 neutron?
Number of electrons with 2 proton and 2 neutron?
Number of electrons with 5 proton and 6 neutron?
Number of electrons with 7 proton and 8 neutron?
Number of electrons with 7 proton and 6 neutron?
Number of electrons with 10 proton and 6 neutron?
Answer these questions about the simulation:
If two separate atoms have the same number of protons, are they the same element or different? (Hint: look at your answers above!)
Answer these summary questions
What determines which element an atom belongs to?
Where did the neutron (gray) end up in the atom?
Where did the electron (blue) end up in the atom?
If two separate atoms have the same number of neutrons, are they the same element or different? (Hint: look at your answers above!)
What do atoms of the same element have in common?
How many electrons does an atom need to be neutral?
Which subatomic particles exist in the nucleus (center) of the atom?
Which subatomic particles exist in orbit around the outside of the atom?
What determines if an atom is neutral?
