Chapter 2 Crib Notes – THE PERIODIC TABLE                                        Name:

20 pts

Smart Guys:

Mendeleev – father of the Periodic Table

Moseley – arranged the PT by increasing atomic number based on protons

Cannizzaro – used C-12 to calculate the masses on the Periodic Table

Calculation of the weighted average of an isotope:

{(mass of isotope 1)(its percent as a decimal)} + {(mass of isotope 2)(percent as a decimal)}+ {(mass of isotope 3)(percent as a decimal)} + etc

Effective nuclear charge means that the core electrons shield the outer shell electrons from the positive charge of the nucleus.  The more electrons an element has, the more shielding it will have.

Trends of the PT:  how to back up any question…

1.  as you go across the PT, the level stays the same, but the number of protons electrons, and neutrons increases, this creates more attraction between the increasingly positive nucleus and the electrons that are close to that nucleus

2.  as you go down the PT, the number of levels increases.  This causes more shielding as the inner shell electrons counteract the positive nucleus and the outer shell electrons in the s and p orbitals are not as bound to it

Atomic and ionic radii:  decrease across the period, increase down a group

Electronegativity, Ionization Energy, Electron affinity: increase across the period, decrease down a group

Melting and Boiling Points of Metals:  decrease as you go down a group

Melting and Boiling Points of Non-Metals:  increase as you go down a group

Free response questions:  20 pts – write answers on a separate piece of paper and staple it…

1.  Compare an alkali metal to a halogen. 

HINT:  This is a good time to bring out what you know about the periodic table.  Discuss where they are located specifically on the Periodic Table (block, period, group, give their shorthand to show reactivity or lack thereof).  Compare them based on their:  electronegativity, electron affinity, ionization energy, atomic radii, ionic radii, metallic character… (10 pts)

2. Compare sodium with chlorine.  Who is the better cation?  Why?  Draw orbital notation (boxes) to explain your answers, discussing the trends of the Periodic Table.  Now compare sodium with rubidium, both in the same group.  Who is the better cation?  Why? Be sure to discuss which side of the Periodic Table wants to gain electrons and become an anion and which elements want to lose electrons and become cations?  (10 pts)

June Homework and some summer instructions

Here is how we play the homework game in AP Chemistry.  I am more than willing to take care of your grade if you are willing to do the work I ask.  Homework needs to be completed and turned in ON TIME.  If you do not turn it in on time, it will go in as a ZERO, if turned in late it will be lowered 10% each day!!  This would be bad since most assignments are worth around 100 points easy.  REMEMBER TO NOT WRITE IN THE BOOK!!!   I suggest:

1.  Read the chapter over the span of a few days and make a general outline for the chapter.

2.  Try to answer the summary questions based on that outline, looking up answers in the book when necessary.  Even though the outline and the chapter summary questions may overlap, they both need to be done and both will be scored.

3.  Answer the exercises assigned from the book as you are reading the chapter.  These should be done in order on a separate piece of paper and be neat so that I can follow them and score them easily.  You don’t want me grading angry, yo.

CIRCLE any ones you have questions on - when we go over it later you want to be able to remember which ones were weird.

4.  At the end of the chapter, answer the multiple choice questions, GRADE THEM, and circle ones that you have questions on so I may address any that you still do not understand when I see you in class.  Do the same with the free response.  These will be for points.  Show work and actually try them please – don’t just copy them and write down the answers – this is not helping you at all.  I am not the homework police – you need to take responsibility for your education when working the assignments.  I can tell if you are just copying stuff down - I am not a moron.

5.  Use a calculator and the formula sheet that is given in the book.  You need to become familiar with the equations they will give you because it helps us tell what questions that could choose.  You can use a calculator on the free response, but not on the multiple choice section - they removed that option last year.  Thanks a lot!

CH 1.  Para Vs. Diamagnetic/Quantum Numbers      Name:

20 points

Short-hand notation:  use [noble gas before it], then:

s-block:  ns¹ or ns²

p-block:  ns²np ^1-6

d-block:  ns²(n-1)d^1-10

1.  Write the symbol and electron configuration notation for:

potassium

 carbon

manganese

tantalum

2.  Write the symbol and the shorthand notation for:

francium

platinum

lead

osmium

n = levels or periods = 1 thru 7

l = sublevels or blocks = s = 0, p = 1, d = 2, f = 3

m = rooms in the sublevel  s = 0, p = -1,0,+1, d = -2,-1,0,+1,+2, f = -3,-2,-1,0,+1,+2,+3

s = spin, either up +1/2 or down -1/2

3.  Draw the symbol and the last orbital box for these elements.  Then write the four quantum numbers for the last electron in that element:

beryllium

 lithium

nitrogen

molybdenum – it is a jumper!!!!

In a DIAMAGNETIC ELEMENT:  all of the electrons are spin-paired so their sub-shells are completely filled, causing them to be unaffected by magnetic fields

In a PARAMAGNETIC ELEMENT:  they are strongly affected by magnetic fields because their sub-shells are NOT completely filled with electrons.

4.  Which of the elements is diamagnetic?

5.  Which of the elements is paramagnetic?

Quantum Number Activity                  Name:

35 points

Here are the quantum numbers for He thru Ca.  Draw the orbital boxes for each to show where the last electron of that element is. 

Designate each of the following sets of quantum numbers as possible or impossible according to the above.  If the set of quantum numbers is NOT possible, circle the one that makes it so.  If the set of quantum numbers IS possible, draw the orbital box for the last electron of that element.  Do your work here:

Chapter 1 Crib Notes – THE ATOM                           Name:

10 points

Dalton:  Atomic Theory and the Law of Multiple Proportions

Bohr: “solar system of orbits” atomic model

N = principal quantum number, orbits, periods, levels (1 thru 7)

L = AKA “azimuthal” quantum number, blocks, shape of the orbitals, sublevels (s=0, p=1, d=2, f=3)

M_l = magnetic quantum number, orientation of the orbitals, the boxes have assigned numbers: 

M_s=spin quantum number of the electron in that orbital (+1/2 or -1/2)

Diamagnetic = all subshells are filled/paired with electrons, elements are NOT affected by a magnet  (all electrons are paired)

Paramagnetic = all subshells are NOT completely filled/paired with electrons, elements will be affected by a magnet (some electrons are unpaired)

Rutherford:  discovered the nucleus using his gold foil experiment which led to his discovery of the proton, and he also separated radiation into alpha, beta, gamma rays using a magnet.

Thomson discovered the electron using his cathode ray tube experiment and Millikan found the charge and mass of that electron suing his oil drop experiment.

Chadwick discovered the neutron when bombarding a beryllium atom with alpha particles – what fun!

deBroglie – wave/particle nature of light

Rydberg equation:  related energy with the level the electron is on:  E_n = -2.178 X 10 ^-18 J

                                                                                                                                 n ²

The jumpers are:  Ag, Au, Cr, Cu, Mo

Short-hand notation:  use [noble gas before it], then:

s-block:  ns¹ or ns²

p-block:  ns²np ^1-6

d-block:  ns²(n-1)d^1-10

Anytime you see the word “ENERGY” you need to bring out these equations:

c = lѵ    c = speed of light = 3 X 10⁸ m/s                   l= wavelength                  ѵ = frequency

E = hѵ  so:  E = hc/ ѵ

h = Planck’s constant = 6.626 X 10 ^-34 Js

1 m = 1 X 10⁹ nm – need to convert anything meters to nm to find the color of the visible light

Blue = low wavelength, high frequency, high energy, 350 – 450 nm

Red = big wavelength, low frequency, low energy, 650 - 750 nm

Free response question:  write on a separate sheet of paper and attach to this sheet: 10 pts

1.  Write the complete and shorthand electron configuration notation for copper and give the set of 4 quantum numbers for its last electron. (HINT:  pour it all out there)

2.  Be sure to write it as a jumper cuz it is.
