Chem ACS Review Cards Flashcards
(22 cards)
Atom Mass
P = bottom
Mass = P + N = top number
E = P except when non neutral
Atomic Radius/Ionic Radoius/Metallic Character
Left and Down = more positive
Electronegativity and Ionization Energy
right and up = more positive
Longer Wavelength
= red light
Greater Energy
shorter wavelenghts / higher frequencies
KE = hv-0
h = constnat
curvy v = freguency
0 = work function
Unusual Electron Configuration
Cu = [Ar] 4s1, 3d10
Ag = [Kr] 5s1, 4d10
Au = [Xe] 6s2, 5d9, 4f14
Pd = [Kr] 5s2, 4d8
Cr = [Ar] 4s2, 3d4
Unpaired electrons
look at empty spaces, electrons like to be alone
Quantam Numbers
n = any poitive
l = n-1
ml = l (+ thru -)
ms = +1/2 or -1/2
Avg atomic mass given percent abundance
(0.0000) abundance x amu = n
add together n’s
Subatomic Particles
of P, N, E added together
Electornegativity and Bond Polarity
more different electronegativity = more polar
Intermolecular Forces
weakest -> strongest
- London Dispersion = in all atoms
- Dipole - Dipole = when + and - ends of molecules are attracted to eachother
- Hydrogen Bonding = when H bonded to O, N, or F
- Ionic - chemical bond where opposite charges ions are attracted to eachother
Relationship between Intermolecular Forces
Stronger IMF = Stronger boiling point and viscosity
Stronger IMF = LOWER vapor pressure
look back at molecular geometry :(
and the bond angles
sigma and pi bonds`
Single Bond - 1 sigma
Double - 1 sigma, 1 pi
Triple Bond - 1 sigma, 2 pi
Know Nomenclature
also review :9
know how to balance equation
review again
remember stochiometery and limiting reactants
)oajnfl ck
Dilution Equation
M1 x V1 = M2 x V2
go over solubility riules again :(
unfortunate
Ideal Gas Law
PV = nRT
R = 8.314 J/molXK
