Atoms - smallest unit of matter that retains all of the chemical properties of an element States of matter - the physical forms of matter, which include solid, liquid, and gas Liquid - No definite shape (takes the shape of its container) Has definite volume Particles are free to move over each other, but are still attracted to each other Solid - A form of matter that has a definite shape and volume Gas - A state of matter with no definite shape or volume Chemical bonds - link el...

What are carbohydrates and lipids? - Organic compounds that are mostly composed of three types of atom; carbon, hydrogen and oxygen What do carbohydrates do? - provide energy, in the form of sugars like glucose and fructose, but they also make up structures like cellulose, which form the cell wall of plant cells What type of carbohydrate is the most important source of energy? - mono-, di- and poly-saccharides What are mono and disaccharides? - polar and soluble in water What are pol...

Electron configuration for cations - Subtract 1 from exponent of highest n-value orbital (ex. remove from 4s before 3d) Ag+ = [Kr]5s^1 4d^9 Electron configuration for anions - Add 1 to closest orbital Cl- = [Ne]3s^2 3p^6 Atomic orbitals - s, p, d, f Primary vs secondary structures of proteins - Primary - AA chain (linked by peptide bonds) Secondary - stabilized by non-covalent bonds (alpha helices & beta sheets) Most bonds in organic compounds are - covalent Properties of...
