The ion 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.

Transcribed Image Text: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.

Transcribed Image Text:2. While a series of events take place
within the airbag system, what
ultimately causes the airbag, stored
in the steering column, to inflate?
to fill up WITH GAS
get bigger USING A GAS
Page 2, Paragraph 2: This ignites the charge which prompts a
deflated nylon airbag (pack or your steering column, dashboard or car door) at about 200 miles par
Page 2, Paragraph 6: A solid chemical mix is held in what is basically a small tray within the steering
column. Then the mechanism is triggered an electric charge heats up a small filament to ignite the
chemicals and BLAMMO-a rapid reaction produces a lot of nitrogen gas. Think of it as supersonic
Jiffy Pop, with the kernels as the propellant.
Page 2 Paragraph 7: A decomposition reaction is a reaction in which a compound breaks down into
er substances
This ignites the charge which prompts a decomposition reaction that fills the deflated nylon airbag (packed in
your steering column, dashboard or car door) at about 200 miles per hour. The whole process takes a mere 1/25
of a second. The bag itself has tiny holes that begin releasing the gas as soon as it's filled. 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.
Manufacturers use different chemical stews to fill their airbags. A solid chemical mix is held in what is
basically a small tray within the steering column. When the mechanism is triggered, an electric charge heats up
a small filament to ignite the chemicals and BLAMMO!-a rapid reaction produces a lot of nitrogen gas.
Think of it as supersonic Jiffy Pop, with the kernels as the propellant.
This type of chemical reaction is called "decomposition". A decomposition reaction is a reaction in which a
compound breaks down into two or more simpler substances. A reaction is also considered to be decomposition
even when one or more of the products are still compounds.

What do we call the colors given off by each atom? 2) Bohr described the atom as a multi-story building and said that the elements could only live on the floors and not in-between. He said that sometimes they jumped from one floor down to a lower floor. Describe what happens when these jumps occur. 3) What did the color of the spectra emitted by an element determine? 4) What is the difference between the ground state and the excited state of an electron?arrow_forward

Using equations he develops, he is able to predict the exact arrangement of electrons in many atoms, and from there predict why they are where they are in the Periodic Table.
