what are the oxidation numbers for transition metals?
527698
Because transition metals have more than one stable oxidation state, we use a number in Roman numerals to indicate the oxidation number e.g. Iron(III) chloride contains iron with an oxidation number of +3, while iron(II) chloride has iron in the +2 oxidation state.

Transition Metals This means that manganese (Mn) has the electron configuration [Ar]4s²3d⁵ and 7 valence electrons.

Locate the transition metal on the periodic table and make note of the group number. Use iron as an example, a transitional metal with the symbol Fe, atomic number 26 , located at period 4, group 8. The element iron is in group 8, and therefore has two or three apparent valence electrons.

There are three noteworthy elements in the transition metals family. These elements are iron, cobalt, and nickel, and they are the only elements known to produce a magnetic field.

The central block of the periodic table contains the transition metals. These can have several oxidation states and are important in producing colored glazes, particularly the metals along the top row: chromium, manganese, iron, cobalt, nickel, and copper.

We can obtain oxidation numbers by arbitrarily assigning the electrons of each covalent bond to the more electronegative atom in the bond. This is in contrast to the Formal Charge which divides each bonding pair equally without concern for which atom may be more electronegative.

Oxidation numbers represent the potential charge of an atom in its ionic state. If an atom's oxidation number decreases in a reaction, it is reduced. If an atom's oxidation number increases, it is oxidized.

In the first row of the transition metals, the ten elements that can be found are: Scandium (Sc), Titanium (Ti), Vanadium (V), Chromium (Cr), Manganese (Mn), Iron (Fe), Cobalt (Co), Nickel (Ni), Copper (Cu), and Zinc (Zn). Below is a table of the oxidation states that the transition metals can or cannot form.

So we use Ar electron configuration and add 10 more electrons. Since Ni is a petiod 4 transition metal, it will have 3d valence electrons. So, the abbreviated configuration for Ni is [Ar] 4s2 3d8.

The transition metals are in Groups 3 through 12 and include iron, copper, nickel, gold, and silver. Most of these metals are hard and shiny solids. ... Except for mercury, the transition metals have high melting points and high densities. They are good conductors of heat and electric current, and are very malleable.

Transition Metals So the valence electrons for a transition metal are the ns and (n-1)d electrons. This means that manganese (Mn) has the electron configuration [Ar]4s²3d⁵ and 7 valence electrons.

Oxidation state is the charge of the central transition metal if all the ligands were removed. Coordination number is the total number of bonds or attachments between the central transition metal and its ligands.

The nitrate (B), dichromate (C) and permaganate (E) ions act as powerful oxidising agents under suitable conditions. The central atoms - N, Cr, Mn- are in their maximum possible oxidation states of +5, +6 and +7 in these species and so they cannot act as reducing agents.
