The octet question is an example. You are not answering that question. It's just an example of how your answer should look for the other question.

 

Use evidence from the text and try to be detailed you can include prior knowledge you may know as well.

1) What is an ion? Explain the difference between a monatomic and polyatomic ion. An ion is a charged atom with #protons # # electrons. On page three, paragraph one reads, "The prefix poly- means many, and atomic refers to atoms. An ion with more than one atom is a polyatomic ion. As a result, polyatomic ions differ from monoatomic ions, which contain only one atom." Polyatomic ions are groups of covalently bonded atoms, where the total number of protons is not equal to the total number of electrons. Atoms become ions when they gain or lose electrons and this results in a net charge. On page two, the ionic compound image shows an ionic bond formed between aluminum (Al) and chlorine (CI). In this image, Al+3 is a monoatomic ion as it is composed of one atom. AIC13 is a polyatomic ion because there is more than one atom involved.

3. Compare and contrast the properties of an effective airbag versus an ineffective airbag. Page 1, Paragraph 4: Airbags must do their work quickly because the window of opportunity... lasts only milliseconds. Page 2. Paragraph 2: The whole process takes a mere 125 of a second. The goal is for the bag to be deflating by time your head hits it. That way it absorbs the impact, rather than your head bouncing back off the fully inflated airbag and causing you the sort of whiplash that could break your neck.
