ERS120H5 Lecture Notes - Covalent Bond, Specific Gravity, Chemical Formula
Document Summary
The atom: approximately same number of positive of neutral neurons, composed of a nucleus, mass of the atom = nucleus. Outer shells: approximately same number of negative electrons. Element: grouping of same atoms that all have same # of protons (and neutrons: e. g. carbon, oxygen, quality of the element has to do with the number of protons it contains. Is ice a mineral: naturally occurring : yes, solid : yes (when its cold, orderly internal arrangement : yes snowflake six sided symmetry, definable chemical composition : yes (h20, inorganic : yes. Mineral properties: crystal form how it grows what shape is it (cubic, hexagon, cleavage how it breaks (repeated, ex. Quartz doesn"t cleave at all: colour clear, white, semi transparent, etc, observable from far ^ Therefore vitrious: streak when rub it and powder comes out powdered colour of minerals, hardness, specific gravity, other: reacts w/ acid, magnetic, salty.
