Answer:
all have trigonal shape
Explanation:
Trigonal planar is a molecular shape that results when there are three bonds and no lone pairs around the central atom in the molecule. The pairs are arranged along the central atom's equator, with 120° angles between them. ... The carbonate ion (CO32-) has a trigonal planar geometry.
