# Practice With a Linear Combination of Atomic Orbitals

## Prompt

“Consider a 3-chain potential well system with separation distance $a$. Sketch the first three eigenstates for this system in real space.”

## Context

This SWBQ gives students the chance to practice drawing the allowed envelope functions of an electron and compare the graphical representation to the values given by inserting information into the LCAO function. After learning how to represent an electron in a potential landscape as a linear combination of atomic orbitals, some students are still not sure how to use the function effectively.
