its used in molecular geometry. it refers to molecules with the shape including one atom at the center of 3 surrounding atoms attached at approximately 120 degree angles. Planar simply means that there are three, connected carbon centers that are each trigonal planar. for a good example look up the shape of propane. its defined as having trigonal planar structure, but i don't really know why that is being as the middle carbon atom only has 2 attached atoms... but yea that's it.
Trigonal pyramid will be its molecular shape. It will have tetrahedral electron domain geometry.
I would think tetrahedral.But I am rusty, so it could be trigonal pyramidal.
The nitrate ion (NO3-) has a trigonal planar molecular shape, with a symmetrical arrangement of the three oxygen atoms around the central nitrogen atom. This shape is due to the three electron pairs surrounding the nitrogen atom repelling each other to maximize the distance between them.
(CO3)-2 forms a symmetrical planar molecule, so that means it's non-polar.
It will be trigonal planar in terms of electron domain geometry, and bent in terms of molecular geometry. Carbon will form a single bond with each hydrogen atom, and will have 2 electrons left over. A molecule with 2 bonding domains, and one non-bonding domain takes on a bent shape.
trigonal planar
CO32- is trigonal planar, bond angles are 1200

The amide ion has a trigonal planar shape, with a nitrogen atom at the center surrounded by three atoms in the same plane.
The bond angle between the oxygen atoms in a carbon dioxide molecule is 180 degrees. This is because the molecule has a linear geometry, with the carbon atom in the center bonded to each oxygen atom on opposite sides, creating a straight line.
(CO3)-2 forms a symmetrical planar molecule, so that means it's non-polar.
PH3 forms a trigonal pyramid ClO4- forms a perfectly regular trigonal pyramid, known as a tetrahedron BeCl2 ~APEX
The NO2^- ion is expected to have a bent shape due to its trigonal planar molecular geometry with a lone pair on the nitrogen atom, which causes repulsion that distorts the bond angles. This results in a bent molecular shape with a bond angle of approximately 134 degrees.
It is a trigonal planar structure - the nitrogen atom in the center.
The hybridization of the valence electrons on the nitrogen atom in NO+ is sp. The electron pair geometry is linear, and the shape of the ion is also linear.
