Book notes: chemical principles 6th ed. by atkins and loretta. Systeme international (si) chart (source: chemical principles, atkins and loretta) Derived units: when units are combined to denote a property more complex than mass, length, time. Extensive property: dependent on the amount of the sample: intensive property: independent of amount of sample, eg. density, changing the mass changes the volume in the same proportion, so the ratio of mass to vol. stays the same. Significant figures: the number of digits that can be justified by data . Accuracy: closeness of the average value of measurements to the true value. Precision: the proximity of repeated values to each other. 3: epsilon 0: vacuum permittivity (8. 854 x 10^-12, charge of electron: 1. 602 * 10^-19. The organization of the elements: 88/114 elements (2013) are considered naturally occurring, classifications, groups, main groups (1, 2, 13-18, periods, blocks (s, p, d, f, transition metals.
