Cards (183)

  • Mass spec steps
    Vaporization, Ionisation, Acceleration, Deflection and Detection
  • AAS Ananlytical Techniques

    Flame Emission and Absorption
  • AAS relies on
    Electron transfer between energy levels
  • Flame Emission Test
    Releases energy as a photon of light
  • Atomic Absorption
    Absorbs energy
  • Sub levels
    s, p, d and f
  • Aufbau rule

    Electrons fill lowest energy first
  • Hunds
    Electrons fill single before doubling (do not share)
  • Pauli Exclusion 

    Electrons oppose if they have to share
  • Exceptions for electron configuration
    Chromium and Copper
  • Trend: Ionisation Energy
    ^ >
  • Trend: Electronegativity
    ^ >
  • Trend: Atomic Radius
    v <
  • Trend: Nuclear charge
    ^ >
  • BAA
    Basic Amphoteric Acidic
  • Isotopes
    Same element, different neutrons
  • Isotope properties (e, chem, phys)

    Same electron configuration, similiar chemical, different physical
  • Pure substances types

    Elements, compounds
  • Heterogenous vs Homogeneous
    Homo = same, Hetero = diff
  • Ionic with

    metal + nonmetal
  • Convalent with
    non + non
  • Strong bond means stronger intermolecular force, therefore greater melting and boiling points
  • Ionic properties
    Strong bonds
    High melting and boiling
    Conducts liquid
    Hard
  • Metallic properties
    Strong bond
    High melting and boiling
    Conducts always
    Hard and soft
  • Convalent Properties

    Weak
    Low melting and boiling
    No conductivity
    Soft
  • Layer Properties

    Weak
    No conductivity
  • Network Properties
    Strong bond
    High melting and boiling
    Conduct solid
  • Heat vs Temperature
    Heat is a form of energy, Temperature is the kinetic energy of particles
  • Exothermic releases excess energy (-)
  • Endothermic absorbs energy (+)
  • Factors that can affect rate of reaction
    Concentration, Temperature, Pressure, Surface area, pressure and catalyst
  • For a reaction to occur, particles must: collide, have sufficient energy and have correct orientation
  • Activation energy
    Minimum energy required for a reaction to occur
  • Acid + Base
    Salt + H2O
  • Acid + Carbonate
    Salt + H2O + CO2
  • Acid + Metal
    Salt + H2
  • Acid + Metal Oxide
    Salt + H2O
  • 4 kinetic gas rulesand proportions

    Boyle: PV = PV, inv
    Charles: V/T = V/T, pro
    GayIssac: P/T = P/T, pro
    Avagrado: V/N = V/N, pro
  • Like dissolves Like
  • Mobile phase
    High affinity to mobile, little absorption to stationary
