I believe it cannot be solved -- levels 1 through 49 were not that difficult -- there is a logic to follow -- level 50 defies the logic and rules so it is not able to be solved.

There is a glitch to do this. Just consult the level '3D level glitch' for more info
5d+3d = 15 8d = 15 d = 15/8 = 1.875
3d + 8 = 2d - 7 3d -2d = -8 - 7 1d = - 15 d = -15
The cast of Level 3D - 2009 includes: Christian Pfeil as Business Man
3d+8=2d-7 3d+8-8=2d-7-8 (substract 8 on both side) 3d=2d-15 3d-2d=2d-2d-15 (substract 2d on both side) d=-15
A pentagonal prism has 15 edges
The 4s orbital should fill before the 3d orbital. This is because the 4s orbital has a lower energy level than the 3d orbital, according to the aufbau principle.
The 3d sublevel can hold a maximum of 10 electrons.
