Write what each word means, using the article.

Do not copy the article. Write two things you learned, the way you would explain them to a friend.

Answers below are taken from the article’s stored facts, so they match what the student read.

1. What is the quantum mechanical model?Describes electrons in terms of probability distributions (orbitals) rather than fixed paths
2. What is the wave-particle duality?Subatomic particles, including electrons, exhibit both wave-like and particle-like properties
3. What is an atom?An atom is the smallest piece of a chemical element that keeps its identity. It has a tiny center called a nucleus and a cloud of electrons around it.
4. Why does an atom have a nucleus?The nucleus is where the atom’s mass is concentrated and it holds the atom together with a strong force that keeps protons and neutrons close.

Atomic Orbital: A region around an atom's nucleus where an electron is likely to be found.
Valence Electrons: Electrons in the outermost shell of an atom, involved in chemical bonding.
Isotope: Atoms of the same element that have different numbers of neutrons.
Quantum Mechanics: The fundamental theory in physics describing nature at the smallest scales of energy and matter.
