Ions
• Atoms will gain or lose electrons to try and become like a noble gas….ie, a complete outer energy level of electrons
• That goal is 8 electrons in the outermost shell• (+) ions have lost electrons• (-) ions have gained electrons

3. Draw a periodic table and label: group and period
![Page 9: CH 5/6 REVIEW Blue = Questions for prize points Pink = review of concepts (notes???) Can only use planner, no book or internet!](https://reader036.fdocuments.in/reader036/viewer/2022062518/56649ea25503460f94ba5a4e/html5/thumbnails/9.jpg)
Groups go down
Periods go across

4. If wavelength = 3.4 x 10-7 m, what is the frequency?
![Page 11: CH 5/6 REVIEW Blue = Questions for prize points Pink = review of concepts (notes???) Can only use planner, no book or internet!](https://reader036.fdocuments.in/reader036/viewer/2022062518/56649ea25503460f94ba5a4e/html5/thumbnails/11.jpg)
Light as a wave
• Which wave will hit wall first?• Which wave has a longer wavelength?• Which wave has a higher frequency?
![Page 12: CH 5/6 REVIEW Blue = Questions for prize points Pink = review of concepts (notes???) Can only use planner, no book or internet!](https://reader036.fdocuments.in/reader036/viewer/2022062518/56649ea25503460f94ba5a4e/html5/thumbnails/12.jpg)
Light as a wave
• C= constant = speed of light = 3 x 108 m/sec• Wavelength = meters• Frequency = Hertz or 1/sec
![Page 13: CH 5/6 REVIEW Blue = Questions for prize points Pink = review of concepts (notes???) Can only use planner, no book or internet!](https://reader036.fdocuments.in/reader036/viewer/2022062518/56649ea25503460f94ba5a4e/html5/thumbnails/13.jpg)
•3 x 108 = 3.4 x 10-7 (v)
•V= 8.8 x 1014 Hz or 1/sec

5. Draw which direction ionization energy increases arrows on a
periodic table to show

Ionization Energy
• Ionization energy is the amount of energy needed to take an electron from an atom.
• If removing an electron helps to make the atom “happy” (8 outer electrons) it is easy to do.
• If removing an electron makes an atom “unhappy” or “unhappier” then it is hard to do (further from 8 outer electrons)
• The further the electrons are from the nucleus, the easier they are to remove (less energy to do so)

energy of all ?(ignore the noble gases)

electrons from?

increases.

Electronegativity
• Amount of pull an atom has on electrons• The higher the electronegativity, the more an
atom can PULL the electrons towards it
