What is the molecular geometry, or shape, of the molecule shown in the image?

Answer : Trigonal Planar.

Explanation : The molecular geometry of is trigonal planar with symmetric charge distribution on the central atom of Boron. It has three bonds with Boron as the central atom and Fluorine as the peripheral atoms. The molecule which has central atom as boron does not contains any lone pairs on it.

Therefore, it has trigonal planar geometry. As the fluorine atoms are arranged in a form of triangle placing boron in the center.

no, the red giant is the hottest with 2.00.000.000 degrees celsius. while the white dwarf only 25,000 degrees celsius.

it is stable as it is in group 0 which have full outer shells of electrons
