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.
Sulfur trioxide (SO3) molecule is a type of this triognal planar shape.

The ion nitrate has a trigonal planar structure; see the link below.
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.
carbonate ion is having trigonal planar geometry
At first glance, you may assume the NH2- ion takes the form of a tetrahedral shape similar to CH4 or ammonia; however, there are two lone electron pairs. Therefore, like the shape of water (H2O), the shape can be called angular or V-shaped.
Think of the sulfite ion as a molecule with its geometry and dipole moment AND a net charge. The electron pair geometry is tetrahedral and the molecular geometry is trigonal pyramidal and because of its asymmetrical shape and polar bonds, sulfite has a net dipole moment (2.04D ). The ion is polar.
Carbonate ion is in a trigonal planar shape (hint: sp2 hybridization)

PH3 forms a trigonal pyramid ClO4- forms a perfectly regular trigonal pyramid, known as a tetrahedron BeCl2 ~APEX

It is a trigonal planar structure - the nitrogen atom in the center.
Trigonal Planar Electronic Geometry Geometry of Molecules: Trigonal Planar Three oxygen atoms are joined to the nitrogen atom in the NO3- ion to create a center atom. The configuration is trigonal planar, and the three oxygen atoms' bonds to the nitrogen atom have roughly 120-degree angles.

The carbonate ion, or CO3 2- has 24 electrons and its structure is trigonal planar. It is non-polar because the trigonal planar is symmetrical.
The electronic shape is trigonal planar.The molecular shape is bent/angular.
