Last updated about 1 month ago
19 questions
Note from the author:
Follow these directions in the simulation:
1. Select the "Atom" activity
2. Click and drag all of the electrons (blue) onto the atom in the center of the screen.

Note: The inner blue dashed line is the "first shell" and the outer blue dashed line is the "second shell".

Answer the following questions about the simulation
Required
1

How many electrons are in the first "shell"?

Required
1

How many electrons are in the second "shell"?

Follw these directions in the simulation:
  1. Select the "Atom" activity.
  2. Build an atom that has 4 protons (red), 5 neutrons (gray), and 4 electrons (blue).
  3. Notice that the message above and right of the atom reads "Neutral Atom".
  4. On the right middle of the screen, click the green plus sign on the "Net Charge" box to view the net charge.
  5. Repeat the experiment with the different numbers of protons, neutrons and electrons listed in the questions below.
  6. IMPORTANT: Please format your answer as such "Neutral Atom or Ion, Net Charge"
Example: + Ion, +3
