💡 Key Takeaways
- Identify the basic building blocks of matter: atoms, elements, and compounds.
- Explain how atoms bond to form molecules and how these structures determine material properties.
- Describe key types of chemical reactions and the governing laws, such as conservation of mass.
- Distinguish physical and chemical properties and changes to understand the structure and behavior of matter.
❓ Frequently Asked Questions
What is the difference between an element, an atom, and a compound?
An element is a pure substance made of only one type of atom. An atom is the basic unit of an element. A compound is a substance formed when atoms of different elements bond in fixed proportions.
What is a molecule?
A molecule is the smallest unit of a substance that retains its chemical properties, formed when two or more atoms bond together. It can be a single element (e.g., O₂) or a compound (e.g., H₂O).
What is a chemical reaction?
A process in which reactants undergo chemical changes to form products by breaking and forming bonds; atoms are rearranged and mass is conserved.
What are the basic laws that govern chemical reactions?
Conservation of mass: mass is not created or destroyed in a reaction. Definite proportions: a compound has fixed ratios of elements by mass.
