Nomenclature Flashcards

1
Q

How are elements classified

A

1.Metals- solids(except mercury) with high electrical and thermal conductivity
2.Non-metals-gases or solids(except bromine)-without metallic characteristics
3. Metaloids/semi-metals-have characteristics between metals and non-metals

Q

What are inorganic compounds

A

They contain all the rest of the elements, including some carbon based compounds(CO,CO2, carbides(C+metal/semi-metal), carbonates(XCO3(CO3^2-)) and cyanides(-CN(CN-))

Q

What kind of formulas exist

A
  1. Molecular formula-nature and the actual number of different types of atom in a molecule. It uses chem symbols and numbers as subscript(ex. H2O)
    2.Structural formula- example H-O-H(showing the rough geometry of the molecule)
    3.Molecular models-different types
    a)space-fillimg model-advantage:sizing and distance; disadvantage:doesn’t show bonds, can’t understand geometry of the molecule
    b)ball-and-stick model-adv:geometry representation: diadv:not accurate sizing, distance is exaggerated
    4.Empirical formula-putting simbols with subscipts that give the simplest possible formula expressing the composituon(ex.H2O2==>HO)

Q

What is oxidation and reduction

A

-Oxidation-loss of e-. oxidizing reagent-removes e- from something else
-Reduction-gain of e-.reducing reagent-gives e- to something else.

Q

How are names of monoatomic cations with many oxidation states given

A

The oxidation state is given in brackets in Roman numerals.
-older sistem uses -ous and -ic where ous is used for Fe2+(2+oxidation state) and -ic for Fe3+(3+ ox.state)
Fe 2+=ferrous ion OR iron(II) ion
Fe 3+= ferric OR iron(III) ion
