Task 2: Explore to develop your own ideas about what makes an atom and how ions are different from atoms. Determine some good rules about the charge of your atom or ion. 1. What is a rule for making a neutral atom which has no charge? 2. What is a rule for making a positive ion which has positive charge? 3. What is a rule for making a negative ion which has negative charge? 1 4. Make a table like the one below to identify three examples of stable atoms and ions. Include 1 with neutral charge, 1 with a positive charge, and 1 with a negative charge. Table 2 Is it a neutral atom, positive Capture and paste your atom or ion What is in your What is atom or ion? the ion, or negative ion? explain why (Stable only) # of protons: 1 # of neutrons: # of electrons: # of protons: 2 # of neutrons: charge? # of electrons: # of protons: 3 # of neutrons: # of electrons:

Can some one please help filling in the empty graph. The other one is to help fill in the empty one . The 6 things I'm listing aren't questions just directions to understand . 1. Correctly round all of your TE values in Trial 5 to a whole number. Correctly round all of your TE values in Trial # 7 to a one decimal place only. 2. Compare the 5 TE values for each trial. Choose the trial in which your 5 TE values are the most similar. This will be your CHOSEN trial . 3. Once you have decided on the trial with the closest 5 TE values, create a bar graph on the attached graph paper. I have labeled the X- axis for you. Notice that you will have a PE, KE, and TE bar for each point. 4. You will have to decide on the numbers for the Yaxis. Type numbers in the blank column on the left of the graph . 5. Remember to title your graph "Y - axis variable name vs X-axis variable name." That is not the actual title, just the template for you to use to write your title. 6. Please make your PE…
