Study Notes
Matter and Its Properties
- Matter: Anything that has mass or occupies space. Fundamental concept in physics and chemistry.
- Mass: Refers to the quantity of matter in an object; a basic measure often confused with weight.
States of Matter
- Solids: Have a defined shape, are hard, and brittle; particles are closely packed and vibrate in fixed positions.
- Liquids: Take the shape of their container; atoms are more mobile compared to solids, allowing them to flow.
- Gases: Fill the available space; molecules are far apart and move freely, rarely interacting with each other.
Special States
- BEC (Bose-Einstein Condensate): State where atoms are close together but possess less energy than in solids; exhibits unique quantum phenomena.
Atomic Structure
- Atoms: The fundamental building blocks of matter; consist of protons, neutrons, and electrons.
- Molecules: Formed when two or more atoms are connected by chemical bonds; can represent compounds or elements.
- Ions: Atoms that have gained or lost electrons, resulting in a charge; crucial in chemical reactions.
Types of Ions
- Cations: Positively charged ions formed by losing electrons.
- Anions: Negatively charged ions formed by gaining extra electrons.
Chemical Fundamentals
- Atomic Number: Represents the number of protons in an atom; determines element identity.
- Periodic Table: Organized chart of elements, arranged by atomic number and grouped by shared properties.
Chemical Grouping
- Families: Columns in the periodic table where elements share similar chemical properties and behaviors.
Chemical Processes
- Dissociated: Refers to the process in which molecules split into individual atoms, crucial in chemical reactions.
Interdisciplinary Science
- Biochemistry: The study bridging biology and chemistry, focusing on the chemical processes within living organisms.
- Steroids: Hormones found within animals; play essential roles in various biological functions.
- Amino Acids: Building blocks of proteins; vital for cellular structure and function.
Organic Chemistry
- Organic Chemistry: The branch of chemistry that studies carbon-containing compounds, emphasizing the diversity and functions of organic molecules.
