Which family has elements that have more than one oxidation number?
transition metals
Can a element have more than one oxidation number?
Yes. Transition metals and halogens other than fluorine are particularly likely to have more than one oxidation number among all their compounds.
Which group has more than one positive oxidation state?
The transition metals (groups 3-12) can have more than one positive oxidation state. When you write the names of compounds with transition metals, you note their oxidation state with roman numerals, e.g. iron (II) oxide and iron (III) oxide.
How do transition metals properties compare with those of elements farther to the left?
The chemical reactivity of transition metals is generally less than that of metals to its left (group 1 and group 2 metals). However, transition metals can exhibit various oxidation states and hence form more number of compounds than group 1 and group 2 elements.
Where is the oxidation number in the periodic table?
The oxidation number is located in the top right-hand corner of each element box; for many elements there is more than one.

transition metals
Can a element have more than one oxidation number?
Yes. Transition metals and halogens other than fluorine are particularly likely to have more than one oxidation number among all their compounds.
What is the oxidation number of hydrogeon when it is combined with a metal?
Hydrogen is a non metal. Metals are electropositive than hydrogen. Therefore, hydrogen atoms in metal hydrides have oxidation number -1.
What do the oxidation number of 2 and -2 imply?
An oxidation number of 2 means the ion has two more protons than electrons. An oxidation number of -2 means the ion has two more electrons than protons.
Which group has more than one positive oxidation state?
The transition metals (groups 3-12) can have more than one positive oxidation state. When you write the names of compounds with transition metals, you note their oxidation state with roman numerals, e.g. iron (II) oxide and iron (III) oxide.
What does the roman numeral tell about an element?
Roman numerals are used to identify the oxidation state of transition metals with more than one possible oxidation state.
Can an element have more than one oxidation number?
Of course they can have.Many elements have several oxidation numbers.
When naming a transition metal that has more than one oxidation number the numeric value of the oxidation number is indicated by a?
Roman Numeral

What is used to name a cation with more than one oxidation number?
Superscript
What is the oxidation number for iron iii?
Iron II is also known as ferrous ions (Fe2+). Ferrous ions, has an oxidation number of +2. The oxidation numbers for the "odd" transition metals that have more than one oxidation number are always the number that is written after the element name (Added:) and it thereby is the charge of it ion. So Fe(III), ferric ion, is Fe3+
How are metals and non metals different?
Metals lose electrons easily, and non-metals gain electrons easily. Metals are ductile; which means they can be stretched out into wire, and non-metals are nonductile.Metals differ from nonmetals merely in that they have a positive oxidation number. An element's oxidation number will be it's charge when it is ionized. For example when sodium (Na) is ionized it will lose 1 electron (to have a complete valance shell) losing this electron (a negative particle) will cause the atom to have a positive charge (and therefore a positive oxidation number too) Non metals will have negative oxidation numbers. When a non metal is ionized it will gain electrons (if it has more than four electrons in it's valence shell gaining electrons takes less energy) when it gains these negative particles it gains a negative charge. The oxidation number is determined by how many electrons are in the valence shell of an electrically neutral atom. Any less than four and the oxidation number is positive so you have a metal, more than four you have a non metal.
