The electron cofiguration of nickel is [Ar]4s1 3d9.
The element with 26 electrons and protons is iron (Fe).
26. Nickel has an atomic number of 28, which means that in a normal state, it would have 28 electrons. Ni+2 means that it oxidized by losing two electrons and would thus have only 26 remaining.
that is only the electron configuration of nickel, a nickel (II) cation would lose the 2 electrons in the 4s and be 1s2 2s2 2p6 3s2 3p6 3d8
The chemical formula for nickel hydroxide is Ni(OH)2.
no. it doesn't
