Unit 3: Matter Flashcards
Key terms in Solids
Strong force of attraction
Fixed positions
Definite shape and volume
Key Terms in Liquids
Indefinite shape
Definite Volume
Faults in the current Particle Model
Particles aren’t solid, inelastic or spheres. Theyre atoms, ions and molecules.
It dosent include the forces between the particles
Very simplified
Crux of Particle Theory
Particles are constantly moving, and this leads to them colliding. Creating pressure.
More temp = more pressure
Amonton’s Law
Boyle’s Law
More pressure = less volume (more vol = less space to collide)
> Small container = more pressure
Charles Law
More volume (more space for collisions) = increase collisions = increased temp
Factors Impacting Pressure
More temp (affected by more volume)
Kinetic energy (affected by more temp, affecting volume)
Name and Define the 3 factors affect the Rate of Diffusion
Concentration Gradient: difference in concentration between A and B, as the particles will try to balance out quicker then theres a greater imbalance between the two.
Temperature: more temp = more energy = faster particles
Surface Area: larger surface area = particles will try to balance out quicker
Shell Capacities
2, 8, 8, 2
Lewis Dot Structure
Element Symbol + Dot for no of valence electrons
Difference in Isotopes
Neutrons
