Concept 3.1: Polar covalent bonds in water molecules result in hydrogen bonding In the water molecule, the electrons of the polar covalent bonds spend more time near the oxygen than the hydrogen The water molecule is thus a polar molecule:The overall charge is unevenly distributed

The Biological Importance of Water B io F actsheet September 1998 Number 30 1 Water is a polar molecule i.e. it has both positively charged and negatively charged areas. Water is made up of two positively charged hydrogen atoms and one negatively charged oxygen atom (Fig 1). Water (H2O) is the most abundant molecule in cells, whole organisms and on earth. This is a consequence of the unique physical and chemical properties of water. This Factsheet will briefly explain the significance of these physical and chemical properties, then discuss the primary roles of water in animals and plants. As a result of this polarity (the uneven distribution of charges), adjacent water molecules are attracted to and become bonded to each other. The

Water is Special Polarity There are two types of covalent bonds, polar and nonpolar While nonpolar molecules share electrons equally, polar molecules do not. This results in one part of the molecule being partially positive and another part being partially negative. 2 Student Misconceptions and Concerns

Composed mainly of nonmetallic elements with simple formulas and low molar masses. Unlike liquids and solids, gases expand to fill their containers. are highly compressible. have extremely low densities. Two or more gases form a homogeneous mixture.
