Chemistry: The Science of Matter
From the atoms that make up your body to the reactions in every cell, chemistry explains the material world. Chemistry vocabulary gives you the tools to understand nutrition labels, medication interactions, environmental processes, and materials science.
Atomic Structure
Every atom has a nucleus (protons + neutrons) surrounded by electrons in orbitals. Atomic number (protons) defines the element; mass number (protons + neutrons) identifies the isotope.
Chemical Bonds
Atoms combine through ionic bonds (metals + non-metals, electron transfer) and covalent bonds (non-metals, electron sharing). Bond type determines whether a substance conducts electricity, dissolves in water, or has a high melting point.
States of Matter
Matter exists as solid (fixed shape and volume), liquid (fixed volume, variable shape), gas (variable shape and volume), or plasma (ionized gas). State changes involve energy exchange without chemical change.
Chemical Reactions
Reactants transform into products by rearranging atoms. The law of conservation of mass requires balanced equations — atoms are neither created nor destroyed, just reorganized.
