Covalent Bonds: two atoms share a pair of electrons, which bond best describes this image?, two non-metals, insoluble in water, low polarity, equally shared electrons, Ionic Bonds: two ions with opposite charges associate together due to a difference in electronegativity, metal and non-metal, high polarity, which bond best describes this image, Polar Covalent Bonds: ex: hydrogen and oxygen bond in water, electron is shared unevenly, electronegativity difference of 0.5 or more, interacts with polar molecules, does not interact with non polar molecules, find the group of best fit, place under group of best fit, Water: polar molecule, hydrophilic (water loving); good solvent/dissolve in water; good sol, hydrophobic (water hating), Hydrogen bonds (Hydrogen atam covalently bonded to an electronegative atom); responsible for other properties of ___., cohesion; stick together, pH of 7 (when pure),
