A. 2s is incorrect, the right arrow should be pointing downwards.
B. In 2p, the last box has 3 arrows. This is invalid. Each box can only store 2 arrows(electrons). The last arrow should be moved to a 3p orbital (new box).
C. In this one, the arrows switched directions (left is down and right is up). You could fix each box or just the last one (in 3p) to point downwards.
3Ni + Sn3(PO4)2 → Ni3(PO4)2 + 3Sn I think. Not for sure though
