Describe a trigonal planar geometry.

Trigonal planar geometry has three atoms surrounding a central atom in the same plane at 120° angles.

What is a tetrahedral geometry?

Tetrahedral geometry involves a central atom bonded to four atoms positioned at the corners of a tetrahedron.

Define trigonal pyramidal geometry.

Trigonal pyramidal geometry occurs when three bonds and one lone pair are arranged around a central atom.

What does bent or V-shaped geometry mean?

Bent or V-shaped geometry occurs when a central atom forms bonds with two other atoms and has one or more lone pairs.

Explain trigonal bipyramidal geometry.

Trigonal bipyramidal geometry involves a central atom bonded to five atoms: three in one plane (equatorial) and two in another (axial).
