Molecular Geometry The true shape of a molecule considering repulsion between lone pairs and bonded atoms. Electron Groups The total number of lone pairs and bonded atoms around a central atom. Lone Pairs Pairs of valence electrons not involved in bonding, affecting molecular shape. Bonding Groups Atoms bonded to a central atom, contributing to the molecule's geometry. Linear Geometry with two electron groups and no lone pairs, forming a straight line. Trigonal Planar Geometry with three electron groups and no lone pairs, forming a flat triangle. Bent Geometry with two bonding groups and one or two lone pairs, forming an angular shape. Tetrahedral Geometry with four bonding groups and no lone pairs, forming a pyramid-like shape. Trigonal Pyramidal Geometry with three bonding groups and one lone pair, resembling a pyramid. Trigonal Bipyramidal Geometry with five bonding groups and no lone pairs, forming two stacked pyramids. Seesaw Geometry with four bonding groups and one lone pair, resembling a seesaw. T-Shaped Geometry with three bonding groups and two lone pairs, forming a T shape. Octahedral Geometry with six bonding groups and no lone pairs, forming an eight-faced shape. Square Pyramidal Geometry with five bonding groups and one lone pair, forming a square-based pyramid. Square Planar Geometry with four bonding groups and two lone pairs, forming a flat square shape.
