Study Notes
Atoms: The Building Blocks of Everything
- Atoms are the tiny building blocks that make up everything around us, from everyday objects to the stars in the night sky.
Structure of an Atom
- An atom can be thought of as a miniature solar system, with a strong core called the nucleus at the center.
- The nucleus is made up of even smaller particles called protons and neutrons.
- Electrons, which are even smaller, orbit around the nucleus like planets around the sun.
Properties of Atoms
- The number of protons in an atom's core determines what kind of element it is (e.g., oxygen or carbon).
- Despite being too small to see, scientists have learned a great deal about atoms through studying their interactions.
Quantum Mechanics
- Understanding how atoms work is a branch of science called quantum mechanics, which is still full of mysteries waiting to be uncovered.
Learn about the building blocks of everything around us, from basketballs to stars, and how scientists discovered that atoms are made of even smaller parts.
