linear
yes
The geometry of XeO3 is trigonal pyramid with an unsymmetric charge distribution. Therefore this molecule is polar. (This came from my chemistry book)
trigonal pyramid
PH3 forms a trigonal pyramid ClO4- forms a perfectly regular trigonal pyramid, known as a tetrahedron BeCl2 ~APEX
This is a "trigonal pyramid" or "tetrahedron."
Trigonal planar and tetrahedrral geometries tend to be present in polar molecules.
The shape is trigonal pyramidal Polarity is non-polar
Polar bears are at the very top of the pyramid. They are an apex predator.
The shape is trigonal bipyramidal and all the atoms on the outside are the same so the charges cancel eachother. Nonpolar
The molecular geometry of nitrogen tribromide (NBr3) is trigonal pyramidal. Nitrogen has a lone pair of electrons, causing the three bromine atoms to form a trigonal pyramid around the central nitrogen atom.
A triangular based pyramid has 4 faces, 6 edges and 4 vertices
