Is CH3Cl Polar? If so, which direction does the polarity vector point?
Yes
Draw the Lewis Diagram for CCl4
Write the electron configuration for:
Germanium (Ge)
1s22s22p63s23p64s23d104p1
This type of bond has atoms that "Share" electrons
What is a Covalent/Molecular Bond?
Ionization Energy Increases in these directions
What is up and to the right
Name the atoms between which hydrogen bonding occurs
H - N
H - O
H - F
If a syringe filled with Gas is compressed to a smaller volume, what happens to the temperature of the gas?
The temperature of the gas increases according to:
V1/T1 = V2/T2
Draw the Electron Diagram for:
Strontium (Sr)
Up to grader discretion
In this type of bond an atom will "Donate" electrons to the other
What is an Ionic Bond?
Atomic Radius increases in these directions
What is down and to the left?
~~~FOR 2000 PTS~~~
If a man wakes up, and walks south 100m, then turns 90o and walks due east for 100m and is attacked by a bear. The man kills the bear and walks due North to return to his camp.
What color was the bear?
White, It was a polar bear.
Is purple a color? Why or Why not?
Not if you're a scientist
What is the Electron Geometry of NH3
Trigonal Pyramidal
Which has a larger atomic radius?
Cl or Cl-
What is Cl-
Electronegativity tends to increase in these direction
What is up and to the right?
What intermolecular forces are present in the following Molecule?
London Dispersion
Dipole - Dipole
Hydrogen Bonding
What is the Molecular Geometry of NH3
Tetrahedral
What is the angle between the Chlorines in CCL4
109.5o
Which has a larger atomic radius?
Na or Na+
What is Na?
Why do metals tend to have a positive charge and nonmetals tend to have a negative charge?
Metals tend to give valence electrons and nonmetals tend to gain valence electrons to complete their octet
Describe London Dispersion Forces
Random movement of electrons cause atoms to become temporarily polarized, This polarity causes the nuclei of atoms to repel eachother
What does the term "like dissolves like" describe in terms of molecular polarity.
Polar compounds dissolve ONLY polar compounds, and non-polar compounds dissolve ONLY in non-polar compounds
Is NaOH Polar? If so, Draw the vector indicating polarty.
(Hint: Draw the Lewis Structure first)
Yes, Host will check accuracy of drawing
Define Ionization Energy
Explain why the atomic radius decreases from left to right on the periodic table
Number of protons increase from left to right, and the nucleas gains more "magnetic pull" on the electrons
