does transition metals have more than one oxidation state?

Answer 1

More than one

Answer 2

Yes!!!
Oxidation is the loss of electrons.
The first row of transition metals in the Periodic Table have the following oxidation states.:-

Sc* +3
Ti +1 +2 +3 +4
V +1 +2 +3 +4 +5
Cr +1 +2 +3 +4 +5 +6
Mn +1 +2 +3 +4 +5 +6 +7
Fe +1 +2 +3 +4 +5 +6
Co +1 +2 +3 +4 +5
Ni +1 +2 +3 +4
Cu +1 +2 +3
Zn* +2


Because of electron configurations some oxidation states are more stable (common) than others. For example Iron (Fe) in oxidation state 2 is green in colour a rather unstable and will readily oxidise to oxidation state 3 (brown).
Potassium permanganate (KMnO4) the Manganese is in oxidation state 7 (purple) When used in acid solution it will oxidise another reactant, itself being reduced to oxidation state 2.
Copper in oxidation state 3 is a comparatively rare species.
All the transition metals can be used a catalysts because their oxidation states can subtly change.
Scandium & Zinc (starred) are not strictly transition metals but 'd' block elements. To be a transition element, the element has to have a partially filled 3d block.

Answer 3

Transition metals have several features in common: unlike representative metals, most transition metals have variable valence, meaning that they have more than one possible oxidation—or valence—state. For example, platinum exists most commonly in the +2 and +4 oxidation states, but it can also be found in the +5 and +6 oxidation states.

Answer 4

first of all, sulfur isn't a steel, that's a non-steel. Secondly, transition metals could have extra desirable than one oxidation state because of the fact they are able to variety solid ions and solid compounds in extra desirable than one oxidation state. Transition metals lose their s electrons first, so maximum transition metals, incredibly the later ones interior the table, have a competent +2 oxidation state. regardless of the undeniable fact that, they are able to lose extra electrons to have solid outer electron configurations reckoning on what they are bonded to; as an occasion, iron is solid because of the fact the +2 ion and the +3 ion. The +3 ion is solid because of the fact it leads to a d5 configuration, the place each d orbital holds one electron, while the +2 ion is solid with particular compounds because of the fact the electrons are paired up interior the d6 configuration (at this factor, the d orbitals are no longer degenerate and there's a extra robust potential separation between the d orbitals than the potential it expenditures to pair up electrons). Copper has 2 oxidation states, +a million (which supplies a d10 configuration) and +2 (d9). even nevertheless Cu+ supplies an entire electron shell, which may well be extra solid, Cu2+ is extra in lots of cases considered, because of the skill of Cu to distort its bonding association so as that it has a decrease potential configuration. interior the top, potential outweighs all different concerns.

Answer 5

Transition metals hve more than 1 oxidation state. They also make nice colored compounds.

Answer 6

The simple answer is yes. Having more than one oxidation states is one of the chemical properties that characterises this group of elements. Take Fe for example, you can have Fe 2+(aq) and Fe 3+ (aq) ions. Please look at the properties of transition metals for more details.

Answer 7

due to the small difference in energy between the 3d and 4s subshells,atoms of transition elements can make use of the outer 4s electrons as well as some or all the inner 3d electrons for chemical reactions.hence,they show variable oxidation states.

for example,the two important oxidation states of iron are +2 and +3:

Fe: [Ar]3d6 4s2

Fe(2+): [Ar]3d6 4s0

Fe(3+): [Ar]3d5 4s0

Answer 8

yeah. eg chomium can be in 2 and 3 plus oxidation states.

Answer 9

whoopsy some 1s not done there home work ! lol
they have a formidable number of oxidation states
ie there are lots of them
