If a man wakes up, and walks south 100m, then turns 90^o 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.

What intermolecular forces are present in the following Molecule?

London Dispersion

Dipole - Dipole

Hydrogen Bonding

Describe London Dispersion Forces

Random movement of electrons cause atoms to become temporarily polarized, This polarity causes the nuclei of atoms to repel eachother

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/T_1 = V₂/T₂

Ionization Energy Increases in these directions

What is up and to the right

400

Atomic Radius increases in these directions

What is down and to the left?

600

Electronegativity tends to increase in these direction

What is up and to the right?

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

1000

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
