Questions & Step-by-Step Solutions

What is the main assumption of the quantum mechanical model of the atom? (2023)
  • Step 1: Understand that atoms are made up of protons, neutrons, and electrons.
  • Step 2: Learn that the quantum mechanical model is a way to describe how electrons behave in an atom.
  • Step 3: Recognize that this model assumes electrons are not just tiny particles, but also behave like waves.
  • Step 4: Realize that this wave-particle duality means electrons can show properties of both particles and waves depending on how we observe them.
  • Step 5: Conclude that the main assumption of the quantum mechanical model is this dual nature of electrons.
