Physical
Identify the reactants and products for the electrolysis of water
Reactants = H20
Products = H2 and O2
atomic number= number of protons in the nucleus
Electrons = number of protons in the nucleus
The average atomic mass can be calculated by multiplying the atomic mass of each isotope by the fraction of each isotope present and adding the results.
Ex.
(62.9298)(0.6909) = 43.48 amu
(64.9278)(0.3091) = 20.07 amu
-------
63.55 amu

Polyatomic Molecules

Polyatomic Molecules
Sulfur = 8 = S8
Phosphorus = 4 = P 4
Cations are named the same as their parent atoms, as shown:
K potassium = K⁺ potassium ion
Mg magnesium = Mg2⁺ magnesium ion
Al aluminum = Al3⁺ Aluminum ion
To name an anion consisting of one element, us the stem of the parent element name and change the ending to -ide:
F flourine = F⁻ fluoride ion
Br bromine = Br⁻ bromide ion
etc.
Transition metals
Cr 2⁺ or Cr 3⁺
Fe 2⁺ or Fe 3⁺
Cu ⁺ or Cu 2⁺
Ag ⁺
Cd 2⁺
Zn 2⁺
In classic nomenclature, when the metallix ion has only two cation types, the name of the metal (usually the Latin name) is modified with the suffixes -ous and -ic to distinguish between the two. The lower charge cation is given the -ous ending, and the higher one, the -ic ending
Binary compounds containing two nonmetals you give the first element a prefix- such as mono- or deca- and the second element ends in -ide
