• Protons Identify an Element/atom (2 protons = Helium)• Protons + Neutrons = Atomic Mass/Weight (2 Protons + 2 Neutrons = 4 AMU)• Chemical Properties Reactivity Valence Electrons• Nonreactive (left on periodic table) Reactive (Right on table) = B

• Families/Columns = similar characteristics (A = all Halogens)• Left to Right Metals>Metalloids>Nonmetals>Noble Gases• Families/Columns = similar chemical & physical properties• Same column (S & O are in Same column – NOT on STAIRCASE!)

• 4H2O - Coefficients = # of molecules

• H2O – Subscript = # of Atoms

• 4H2O – Coefficient x subscript = total # of atoms

• Accelerating Speeding up, slowing down, turning.• Velocity straight line with direction• Speed distance travel in any way over time

• Force = Mass x Acceleration (2nd Law)• Action – Reaction (3rd Law)• Motion – Stays in Motion/Rest – Stays in Rest (Inertia/1st)• Balanced = not moving…. Unbalanced = Moving

• Balanced = 0 Net force no increasing speed• F = ma F = 15x5 75

• F = ma a = f/m• Think (bigger bottom # = Smaller answer)• Do Math (50/38 = 1.31, 50/36 = 1.39, 50/21 = 2.38)• LEAST ACCELERATION = Greatest Mass

• Draw lines across H-R Diagram• Hotter but as bright? (D)• Cooler & Brighter than the sun (B)

• Uplifting & push together = mountain• Plates meet > magma > erupting surface• Map of tectonic plates!!

Which world map shows the locations where most earthquakes and volcanoes occur on Earth?

a

c

b

d

• Think Levels• Topographic map = Land Features • Air Pressure Looks similar, but is not elevation!

• Chemical Formula • C6H12O6, H2O, H2O2, Fe2O3

• Can not change ratios!! Change the compound.

In the formation of specific compounds, the elements A always combine in a specific mass ratios.B can combine in several different mass ratios.C always have properties identical to those for the compounds formed D always combine in a 1:1 mass ratio

• Greatest Potential = Highest!!

• Greatest Kinetic = Lowest!!

• They continuously switch

• S = d/t• Need d• 20 = ?/4

• Either 5 or 80• 20 = 5/4• 20 = 80/4

6.8 (C) – Calculate average speed

• Distance / Time– C (remains the

same)

• Speed / Time– B (increasing)

• DE shows change in speed (increasing)

6.8 (D) – Measure and graph changes in motion
