No Element Has that kind of Configuration
Nickel (II) permanganate has the formula Ni(MnO4)2
Because,(i) Ni(II) have d8 electronic configuration, which strongly favors square-planar complex formation;and dmg on loosing one acidic proton favors the square-planar arrangement makes the formation of [Ni(dmg)] complex favorable (ii) Because d8 configuration is stabilized most in square-planar geometry (due to high CFSE) the formation of complex becomes more favorable which adds to the driving force of the complex formation.
Rf values are determined by the polarity of the substance tested. Even though these atoms may have similar electron configuration, it is not identical, and neither are their Rf values.
1 mole Ni = 58.6934g 1g = 1000mg 2.63mol Ni x 58.6934g Ni/mol = 154g Ni 154g Ni x 1000mg/g = 154000mg Ni
no. it doesn't
No Element Has that kind of Configuration

Nickel(II) is the plus two (+2) oxidation state of nickel (Ni), and we write it Ni(II) or Ni++ when we set it down.
Answer 你好 Ni-Hao
Nickel (II) permanganate has the formula Ni(MnO4)2
"你好吗"(ni hao ma)(How are you) "你好啊"(ni hao a) ( How are you) "

The standard model suggests an electron cofiguration for nickel (element number 28)as :[Ar] 4s2 3d8However, relativistic effects make the more stable configuration [Ar] 4s1 3d91s2,2s2,2p6,3s2,3p6,4s2,3d8
