The Oxidation state of Cr is +6.
Also no electrons are available in valence shell of Cr+6 ie it has empty 4s and 3d subshell. Three 3d orbitals ie. 3dxy, 3dyz and 3dzx and One 4s orbital is used.
If you wonder why other orbitals of the d doesn’t come into picture is because they are at high energy level (CFT theory) and it’s easier to form bond with it.
So this makes the hybridisation as d3s.
