In borax bead test, the coloured ions give characteristic coloured beads due to the formation of

1) metal borates

2) metal metaborates

3) metal phosphates

4) metal tetraborates  

For the following metal complexes , provide the: (a) Oxidation states of metal ion and ligands (b) Orbital diagram for the metal cation (c) Coordination number of the metal ion (d) Geometry of the metal ion (tetrahedral, square planar or octahedral, line. [CrCl(NH_3)_5]SP_4 [CrCl_6]^3-
