Here are a few from a list I am compiling, some elements can have multiple charge types, which are notated with the Roman numerals, such as Cu (I) or Au (III):
+1 Charge [Lithium, Sodium, Potassium, Rubidium, Cesium, Copper (I), Silver, Francium, Gold (I), Gallium (I), Indium (I), Thallium (I), Hydrogen, Titanium (I), and Mercury (I)]
+2 Charge [Magnesium, Calcium, Strontium, Barium, Cadmium, Chromium (II), Cobalt (II), Copper (II), Iron (II), Lead (II), Manganese (II), Mercury (II), Nickel (II), Tin (II), Vanadium (II), and Zinc]
+3 Charge [Aluminum, Chromium (III), Iron (III), Vanadium (III), Yttrium, Scandium, Gallium (III), Indium (III), Thallium (III), Bismuth, Arsenic (III), Cerium (III), Cobalt (III), Gold (III), Titanium (III), Manganese (III)]
+4 Charge [Lead (IV), Vanadium (IV), Tin (IV), Cerium (IV), Titanium (IV), Germanium (IV)]
-1 Charge [Fluoride, Chloride, Bromide, Iodide]
-2 Charge [Oxide, Sulfide, Selenide, Telluride]
-3 Charge [Nitride, Phosphide]
-4 Charge [Carbide, Silicide]
Note, this is not a complete list, nor is it 100% assured that it is right. If you find anymore or have problems, leave a note at kyto_beta@Yahoo.com

What is the oxidation number for just sulfur?
The oxidation number in atomic sulfur is 0. With other non metals, it produces many ions where its oxidation number varies from -2 to +6. The oxidation number of sulfide ion (which is produced usually with ions from metals) is -2.
What is THE common oxidation number for tantalum?
It shows some oxidation numbers. Generally it shows +4 oxidation numbers.
Oxidation numbers for five common transition elements?
Transition elements usually have more than one oxidation number. In different oxidation numbers, the ions show different colors. Some of the ranges: Cu from +1 to +2; Cr from +2 to +6; Ni from +2 to +3; Co from +2 to +3 and Mn from +2 to +7.
Does a metal or nonmetal have both positive and negative oxidation numbers?
All metals have positive oxidation numbers. Non-metals may have positive or negative oxidation numbers and some metalloids have both positive and negative oxidation numbers as well
Why must oxidation numbers be assigned to the elements before writing a chemical formula?
The oxidation numbers of the elements in a chemical formula, some of which will be positive and others of which will be negative, when multiplied by the numbers of atoms with each oxidation number, must produce products that add to a net result of zero.

Do ions consist of more than one atom?
Yes; polyatomic ions, such as nitrate, ammonium, etc.
What is THE common oxidation number for tantalum?
It shows some oxidation numbers. Generally it shows +4 oxidation numbers.
What are some common ions with changing oxidation numbers?
Some of the elements exhibiting variable oxidation numbers are carbon (+4, -4); oxygen and selenium (-2 to +6); nitrogen and phosphorus (-3 to +5) halogens (except fluorine) (-1 to +7) and most of the transition metals and f block elements.

Do all elements in a group have the same oxidation numbers?
There is at least one oxidation number shared by all the elements in a periodic table column, but some of the elements may have more than one oxidation number and some of these additional oxidation numbers may not be possible for all the elements in a column.
In a reaction the numbers of some of the elements changes from the reactants to the products?
oxidation
What is the oxidation numbers of sulfur?
The oxidation number is 0 in elemental form. It can have other oxidation numbers as -2, +4 and +6 in its compounds such as H2S, SO2 and SO3 respectively.-2, 0, 2, 4 and 6 oxidation states
How do some atoms gain or lose electrons to form ions?
Oxidation: losing electrons Reduction: gaining electrons OIL RIG (oxidation is losing-reduction is gaining) ^ helpful memory tool.
Are oxyanions acidic solutions?
No. An oxyanion is a negative ion that contains oxygen and some element with a raised oxidation state. An acidic solution is one that contains more hydronium ions than hydroxide ions.
