Chemistry 002: General Chemistry 1 Midterm 1 Study Guide Here are some useful periodic trends from Chapters 2 & 3: In chapter 2: Quantum Mechanics, quantum numbers can be rather difficult concept to grasp. The table below provides a general description of quantum numbers, their labels, and their meanings. To relate quantum number to nodes, there are three simple calculations to consider: 1. Angular nodes are respective to the subshells. Meaning l is equal to the number of angular nodes. 2. Radial nodes are described as n-l-1. 3. Combine the two calculations to determine the total number of nodes: n-l-1+l = n-1. Below I have included a table of quantum numbers ranging from 1s to 4f. Drawing molecules in Chapter 4 requires a considerable amount of visualization. Here is a table that may help. An important factor to remember when drawing molecules is paying attention to lone electron pairs. Lone electron pairs have a greater influence on the shape and degree of angle about the molecule than atoms.
