means that a single water molecule is composed of two hydrogen atoms and one oxygen atom covalently bonded together. This is to say that oxygen and hydrogen atoms are bonded together by shared electrons. The oxygen atom contributes a single electron to both hydrogen atoms to complete the two-electron outer shell of hydrogen while the single electron from each hydrogen atom completes the outer 8-electron shell of oxygen. Water itself is created when a single water molecule forms a hydrogen bond with up to four other water molecules. This means that the partially negative oxygen atoms are attracted to the partially positive hydrogen atoms and form a bond.3. Describe its chemical properties. Water has four main properties:1. Water is an excellent solvent - A solvent is a substance, usually a liquid, in which other substances (solutes) dissolve to form a homogeneous mixture. Many substances dissolve easily and readily in water. Earth's salty oceans are an example of water as a solvent.2. Water is cohesive - Water molecules are attracted to each other due to their ability to create hydrogen bonds. This means that water molecules prefer to stick together. An example of water cohesion is observed when a glass can be filled just above the rim. The attraction of water molecules creates surface tension that prevents water from flowing
