LESSON 1
Quantum Mechanical
Model of the Atom
1. Describe the quantum
mechanical model of the
atom
2. Explain the different
nature of light.
Quantum Mechanical Model
Quantum mechanical model of an atom
describes electrons as waves and not
particles, and how it is based on
probability and not certainty.

Interference
- occurs when waves
combine. An interference can
be constructive or
destructive.
A. Constructive interference
– results when two waves
combine in phase.
B. Destructive interference –
occurs when two waves combine
out of phase.
