What is the electronic configuration of Mn7+
Answers
Answer:
hello mate...
Explanation:
Electronic configuration of Mn2+ is [Ar]18 3d5. Electronic configuration of Fe2+ is [Ar]18 3d6. It is known that half-filled and fully-filled orbitals are more stable. Therefore, Mn in (+2) state has a stable d5 configuration
hope it will help you......
plz mark as brain list answer..
Answer:
The Correct answer for the given question would be :
For S, P, D, F configuration - 1s²2s²2p⁶3s²3p⁶.
For K, L , M , N configuration - 2, 8, 8 .
Explanation:
What is electronic configuration?
Electronic Configuration of an elements refers to the arrangement of electrons n its shells as well as sub-shells. It tells us how many electrons revolve in the first shell, how many in second and so on.
Now, the atomic number of Mn is 25 electronic configuration for manganese (Mn) is 1s²2s²2p⁶3s²3p⁶4s²3d⁵. When it becomes the ion Mn⁷⁺, 7 electrons are withdrawn from it and it is basically remained with 25 -7 = 18 electrons. Hence, going it with same procedure, we'll write configuration for 18 electrons.
