FDSC 200 Lecture Notes - Lecture 6: Unified Atomic Mass Unit, Chemical Formula, Chemical Bond
Document Summary
Compounds 2 or more elements: basic unit molecule, 1 amu (atomic mass unit)= mass of a proton/neutron. Chemical bonding: electrons, shell, 7 shells ionic bonds, electrons transfer, cations, anions. Classification of matter: pure sub all basic units same elements or compounds. Compounds organic (chains or rings of c) or inorganic (no or single c: mixtures (together but not chemically combined) Most homogenous mix solution in which solute dissolved by solvent. Physical and chemical changes: physical change shape, size, t and/or physical state, phase change, chemical change new subs with diff chemical and physical properties are formed. Change in color, odor, flavour, releases gas: may or may not be reversible.
