[Ni(NH₃)6]2+ (Ni₂+, d8) with NH₃ in an octahedral field is high spin, using outer orbitals (sp3d2).
Ref: NCERT Class 12 Chemistry > Chapter 5: Coordination Compounds > Topic: Bonding - Valence Bond Theory and Hybridisation
Primary valence is the oxidation state. In [Fe(H₂O)6]SO₄, H₂O is neutral, SO₄₂− is −2, balanced by [Fe(H₂O)6]2+, so Fe is +2.
