You can check this is correct by adding the number of electrons on each shell, and they will add up to 25 which is the number of electrons of Manganese.

[Ar] 4s2 3d8
[Ar] 3d5 this is the common Mn2+ ion
[Ar]3d54s2
Mn is configured: [Ar] 4s2 3d5 , soMn2+ has an electron configuration of: [Ar] 4s0 3d5It looks like that 5 or 3 or (at least) 1 (one) electrons are to be unpaired.
The electron configuration is incomplete. Assuming that you mean [Ar]4s23dy, here are the possibilities: y=1 Sc y=2 Ti y=3 V y=4 Cr (Actually [Ar]4s13d5) y=5 Mn y=6 Fe y=7 Co y=8 Ni y=9 Cu (Actually [Ar]4s13d10) y=10 Zn Basically the first row of transition metals, since their outermost electron shell is the 3d shell.
O.S of Mn = 3+ O.S. of Cl = 7+ O.S. of O = 2-
Vanadium's atomic number is 23. Thus, it has 23 protons and 23 electrons. The configuration for 23 electrons is 1s2 2s2 2p6 3s2 3p6 4s2 3d3.Vanadium electron configuration is fairly straightforward for a transition metal. Electron configuration is the basis for the oxidation states of a element. You already know that Vanadium is popular in Flow Batterytechnology because has 4 different oxidation states, so the big containers of electrolyte can all be based on a single metal. This makes the batteries a little safer, because nothing terrible happens if the reservoirs of electrolyte accidentally get mixed.Most scientific information about vanadium tops is best read at http://www.vanadiumsite.com
MnO2 manganese(IV) oxide. Oxygen has a -2 oxidation state (oxidation state is a better term here as oxidation number is better used for complexes- they give the same answer for this compound)
Manganese's atomic number is 25. Thus it has 25 electrons. Filling in the first 25 orbitals gives the electron configuration of s2 2s2 2p6 3s2 3p6 4s2 3d5.
Mn is configured: [Ar] 4s2 3d5 , soMn2+ has an electron configuration of: [Ar] 4s0 3d5It looks like that 5 or 3 or (at least) 1 (one) electrons are to be unpaired.
Chemical Symbol: Mn
The electron configuration of a neutral chromium atom is [Ar]3d54s1. The electron configuration for manganese is [Ar]3d54s2. The first electron removed from a chromium atom is the single 4s electron, leaving the electron configuration [Ar]3d5. The first electron removed from a magnesium atom is one of the 4s2 electrons, leaving the electron configuration [Ar]3d54s1. Removal of a second electron from a chromium atom involves the removal of one of the 3d electrons, leaving a configuration of [Ar]3d4, which is not a very stable configuration, and requires more energy to achieve. Removal of a second electron from a magnesium atom involves the removal of the second 4s electron, leaving a configuration of [Ar]3d5, which is more stable and requires less energy to achieve.
MN= Minnesota, therfore yes it is a state.
Outer most shell of Mn contain 2 electron in 4s orbital and 5 unpaired electron in 3d orbital hence in exiting state it has 7 unpaired electron. Thus It shown number of oxidation state................... 0, +2, +3, +4, +6, +7 etc.
Because of stable electronic configuration of Mn electrons are less delocalized and hence they cannot move in electron sea freely to contribute to strong metallic bond. Hence they have low melting points.
There is two dots above the Mn, there your two S dots
ummm...that doesn't make any sense...what state is kimball MN in?? well MN of course!!thats minnesota if that was your question....i live in kimball....
