AX2E3

Why is the AX2E3 shape linear, while the AX2E2 shape bent? Both central atoms have lone pairs.

I think that the AX2E3 shape would be linear because although it has lone pairs on it, the three lone pairs are arranged in such a way that the lone pairs and their repulsions cancel each other out (so to speak) and therefore don't cause the atoms bonded to the central atom to move closer together. The AX2E2 shape is bent because the lone pairs and their repulsion don't cancel each other out.

I agree ^
- The 3 three loan pairs "cancel" each other out in AX2E3 making it linear.
but in AX2E2 the loan pairs do not cancel each other out making the shape to bend
