Question

Within the Hand Method for chemistry, what does 5 fingers represent?

a) Five resonance structures
b) Five ionic bonds
c) Five covalent compounds
d) Five atomic orbitals

Answer 1

In the Hand Method for chemistry, 5 fingers represent the five electron groups around a central atom, arranged to minimize repulsion in a trigonal bipyramid shape.

Step-by-step explanation:

Within the Hand Method for chemistry, the representation of 5 fingers indicates there are five electron groups around the central atom, with a combination of bonding pairs and lone pairs - specifically, two bonding pairs and three lone pairs.

This configuration helps to minimize repulsions by arranging the electron groups in the corners of a trigonal bipyramid, which is crucial for understanding molecular geometry and electron distribution.
