Well I'm trying to replicate this image using geonodes in blender
But I cant figure out how to make the arrays and for some reason the array modfier does not work with the geonodes.
I only did this part:
Does anyone knows how to do that? THANKS!

Array modifier is not working in your case because your spheres are still just instances, not real mesh. Add a Realize Instances node at the end, right before Group Output and it would work as expected. You can then use the "Object Offset" option of the Array modifier with an Empty object to easily reproduce your spiral. If you want to do everything in GeoNodes, here's one way you could:
You've already done the first part and created a rectangular array of sphere instances. I simply added a second array using a Curve Line to stack them vertically. Accumulate Field node here makes it so that the first instance in this second array is rotated 0.150rad on the Z axis, the second instance is rotated 0.300, third instance 0.450 and so on, creating a spiral.
