Which 3d-series of transition metal exhibits the highest number of oxidation state and why?

Which 3d-series of transition metal exhibits the highest number of oxidation state and why?

Mn has the maximum number of unpaired electrons present in the d-subshell (5 electrons). Hence, Mn exhibits the largest number of oxidation states, ranging from +2 to +7.

Which transition metal of 3d-series show variable oxidation state?

1. The first transition metal Scandium exhibits only a +3 oxidation state, but all other transition elements exhibit variable oxidation states by losing electrons from (n-l)d orbital and ns orbital as the energy difference between them is very small.

Which of the following transition metals displays maximum oxidation states?

Manganese shows maximum number of oxidation states because it has 5 unpiared electrons in 3d and also contains 2 electrons in 4s sub-shell.

Why does MN show maximum number of oxidation states in 3d series?

Manganese exists in 6 different oxidation states i.e. from +2 to +7. This is the highest number for any element in the 3d-series. The reason for the existence of such a huge number of oxidation states in manganese is due to the presence of 5 unpaired electrons in its 3d subshell which can show easy transitions.

Which element of 3d series contains maximum number of unpaired electrons in ground state?

Answer : In 3d series of transition metals Manganese shows largest number of oxidation states because it has highest number of unpaired electrons in its -orbitals.So, that by removing its all electrons we get different oxidation states.

Which of the following 3d transition elements show +7 oxidation state?

1) In 3d-series of transition metals, manganese has an atomic number of 25 that gives the electronic configuration as [Ar] 3d54s2 ,where we see that the maximum number of unpaired electrons is found in manganese atom; so, it can show a maximum oxidation state upto +7.

Which transition metal of 3d series does not show variable oxidation states?

Scandium
Scandium (Z=21) does not exhibit variable oxidation states.

What is the maximum oxidation state of osmium?

+8
The highest oxidation state of osmium is +8 due to its ability to expand their octet by using its all 8 electrons (2 from 6s and 6 from 5d).

What is the maximum oxidation number of Mn?

+7
Transition metals are well known for having more than one stable oxidation state. manganese has more than any other. In its compounds manganese exhibits oxidation states from +2 to +7. The common oxidation states are +2, +4, and +7, but the less common +3, +5, and +6 states are easily prepared.

Which transition element has maximum number of unpaired electron?

Only one unpaired electron is present. Hence, the species that has a maximum no. of unpaired electrons is Fe2+.

Which of the following transition elements has maximum unpaired electrons?

Mn2+ ion has maximum unpaired electrons and it has 5 unpaired electrons.
