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.
