Document Summary

React with water vigorously: metal oxides, basic reacts with acids, metalloids, 1,2,13,14,15,16,17, metallic & non metallic physical & chemical properties, gain or lose electrons, amphoteric oxides. Increases production of erythropoietin increases r blood cell: acidic left to right, graphs, magnitude y, atomic number x, atomic radius negative slope, ionization jagged positive slope. Nh3 + h+ nh4: polar covalent bonds, unequal sharing of electrons, polar arrow ( + , + less electronegative atom, more electronegative atom, difference in electronegativity, large intermediate, ionic polar covalent, zero (small) pure covalent, percent ionic character, small generally non metals, large metals & non metals, difference. 1 heme unit: iron & oxygen (4, carboxyhemoglobin, <50 ppm: upper safety limit, 50 200ppm: headache/nausea, >200ppm: dizziness/convulsions, saturation with o2 reverses process, binds better because of polarity. Water in biology: polar molecule, attaches to ions transmembrane movement, helps to folds proteins, determines how molecules bind to receptors, abundant, high boiling point (100 celsius)
