Final Exam Flashcards
Boyles Law
As pressure increases volume decreases
P1V1=P2V2
Inversely proportional
Charles Law
As temperature increases volume increases
Directly proportionate
V1/T1 = V2/T2
Degrees in Kelvin
Gay Lussac Law
As pressure increases temperature increases
P1/T1 = P2/V2
Units of pressure
1 atm= 101.3 kpa = 760 mm Hg = 760 Torr = 14.7 psi
Combined gas law
P1V1/T1 = P2V2/T2
Ideal gas law
PV=nRT P= pressure V= volume n= moles R= constant T= temperature in Kelvin
Kelvin Temperature
Degrees celsius + 273
Orbital
Area where an electron is most likely found
S p d f
Where is the electron
S - starts in energy level 1/ 1 orbital w 2 electrons/ sphere shape
P - energy level 2 orbital 3/ 6 electrons/ dumbell shape
D- energy level 3 orbital 5/ 10 electrons flower shape
F- energy level 4/ 7 orbitals 14 electrons
Electron configurations
Rules
Aufbau principle- electrons enter the lowest energy level
Hans rule- electrons enter different orbitals of the same energy level
Pauli Exclusion- max 2 electrons must have opposite spins
Wavelength
Length of the wave
Frequency
of waves per second
The periodic table
Patterns
Rows and Families
Electronegativity
Ability of an atom to attract electrons
Increase from left to right- atoms are smaller with greater nucleur charge (same electrons in level but more protons means they are pulles tighter together )
Decrease from top to bottom- more energy levels
Ionization Energy
Energy required to remove the electron of the outermost energy level
Increase from left to right- atoms are smaller with greater nucleur charge (same electrons in level but more protons means they are pulles tighter together )
Decrease from top to bottom- more energy levels
Atomic Radius
Half the diameter of an atom, found by the distance between the nuclei of 2 bonded atoms
Increase top to bottom bc more energy levels
Decrease left to right bc greater nucleur charge
Acid
Produces H3O when dissolved in water
Increases by 0s ( 2=10 4=1000)
