📝 Quick Notes: Key Points from the Lesson
1️⃣ What are Atoms?
Atoms are the smallest units of matter.
Made up of protons, neutrons, and electrons.
2️⃣ The Structure of an Atom
Protons (+): Found in the nucleus, positive charge.
Neutrons (0): Found in the nucleus, neutral charge.
Electrons (-): Orbit the nucleus, negative charge.
3️⃣ Elements & The Periodic Table
An element is a substance made of only one type of atom.
The Periodic Table organizes elements based on their properties.
4️⃣ What are Compounds?
Compounds are substances made of two or more different atoms chemically bonded together.
Examples: Water (H₂O), Carbon Dioxide (CO₂), Sodium Chloride (NaCl).
5️⃣ Mixtures vs. Compounds
Mixtures are physically combined (e.g., air, saltwater).
Compounds are chemically combined (e.g., H₂O, CO₂).
6️⃣ Writing Chemical Formulas
H₂O (Water) → 2 hydrogen atoms + 1 oxygen atom.
CO₂ (Carbon Dioxide) → 1 carbon atom + 2 oxygen atoms.
NaCl (Salt) → 1 sodium atom + 1 chlorine atom.
