NWTC Chemistry Final Exam – Comprehensive Study Guide and Exam Preparation
Material
Which states of matter have definite volume? Definite Shape? - ✔✔Volume is solid and liquid.
Shape is only solids
What is the difference between homogeneous and heterogeneous mixture? -
✔✔Homogeneous is the same throughout where hetero is not evenly mixed. Example: Homo-
Salt/Water Hetero: Salt/Pepper
How many Kelvin are in 46 Degrees Celsius? - ✔✔46 + 273 = 319K
Alkali Metals - ✔✔Group 1
Alkaline Earth Metals - ✔✔Group 2
Non Metals - ✔✔Top right of steps
Metals - ✔✔Left of steps
Metalloids - ✔✔On steps
Halogens - ✔✔Group 17
Noble Gases - ✔✔Group 18
Atomic Radius Trend - ✔✔Left and Down
, Ionization Energy Trend - ✔✔Right and Up
Which elements are diatomic? - ✔✔H, N, O, F, Cl, Br, I
What charge does a cation have? - ✔✔Positive
What charge does an anion have? - ✔✔Negative
Physical Properties are? - ✔✔Doesn't change chemical makeup, change in shape, boiling point,
freezing point, conductivity
Chemical Properties are - ✔✔Changes chemical makeup, reactivity, flammability,
decomposition
How did Rutherford's gold foil experiment work? - ✔✔Alpha particles were shot at a thin gold
foil and there were mixed results. Some went through, some hit the nucleus and bounced and
others were deterred because of the charge. Helped find out their was a nucleus and that an
atom was mostly empty space.
An ionic bond is between a ----- and a ----- which involves the ----- of electrons. - ✔✔Metal
Nonmetal
Transfer
Covalent bonds are between ----- and ----- which involves the ------ of electrons - ✔✔Nonmetal
Nonmetal
Sharing
