CH 5/6 REVIEW

Blue = Questions for prize pointsPink = review of concepts (notes???)

Can only use planner, no book or internet!

1. Write the electron configuration and orbital notation for an Oxygen

atom

30 seconds

• An orbital notation is the boxes and arrows• 1s 2s 2p• An electron configuration is the

superscripts:•1s22s22p4

2. Write the electron configuration and orbital notation for an Oxygen

ion.

30 seconds

O-2

• An orbital notation is the boxes and arrows• 1s 2s 2p• An electron configuration if the

superscripts:•1s22s22p6

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

Add the following ion charges to your periodic table….

3. Draw a periodic table and label: group and period

Groups go down

Periods go across

4. If wavelength = 3.4 x 10-7 m, what is the frequency?

Light as a wave

• Which wave will hit wall first?• Which wave has a longer wavelength?• Which wave has a higher frequency?

Light as a wave

• C= constant = speed of light = 3 x 108 m/sec• Wavelength = meters• Frequency = Hertz or 1/sec

•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)

6. Which atom on the periodic table has the highest ionization

energy of all ?(ignore the noble gases)

Fluorine

7. Which atom on the periodic table is the easiest to remove

electrons from?

Francium

8. Draw arrows on periodic table to show how electronegativity

increases.

++

Electronegativity

• Amount of pull an atom has on electrons• The higher the electronegativity, the more an

atom can PULL the electrons towards it

9. Which atom on the periodic table has the highest

electronegativity?

Fluorine

10. Which element on the periodic table has the lowest electronegativity?

Francium
