can you place 8 queens on a chessboard without them being able to "eat" eachother?

Yes. For example (ignore the kings):

2Q1k3/Q7/6Q1/4Q3/7Q/1Q6/3Q4/5QK1 b - - 0 1

what do you mean for example?

this is the only possible structure, all other possibilities are just rotations of this one

right?

The real fun is trying to find them by yourself, when I tried I could only find 88 (distinct), the missing 4 are really nice with their rotational symmetry now that I see them.
