Description
• molecule still electrically neutral, but has charged parts • one end (pole) is slightly negative • one end (pole) is slightly positive Hydrogen bonds - basic fundamental way as to why water molecules stick together -occurs when slightly (+) hydrogen atom from one polar covalent bond attracted to the slightly (-) atom of another polar covalent bond -very temporary - bond b/w molecules - hydrogen bonds occur b/w polar molecules - individually weak, but there tends to be a lot of them - usually temporary - very important in living organisms & biological systems PROPERTIES OF WATER (2.4) -2 hydrogen atoms covalently bonded to 1 oxygen atom -Charged electrons are closer to the O than the H -It’s a polar molecule ( a little +, a little -) -The reason life exists as we know it is because there’s so much water (abundant in nature) -The reason why it’s important is explained by the hydrogen bond -Properties of water (created by the hydrogen bond): • Adhesion-water molecules sticks to other su
