The words “hydrogen ion” and “proton” can be used interchangeably.1 True False Which one of these does a water molecule NOT do?1 share electrons with other molecules vibrate dissolve a lot of substances split apart Regular water never has any ions (H+ or OH-) in it.1 True False What do you call H3O?1 hydrogen ion ozone hydronium ion hydroxide ion Water is a polar molecule.1True / False True False What percentage of an adult human body is water molecules?1 80 percent 60 to 70 percent 30 to 40 percent 50 percent What is another name for a hydrogen ion?1 Electron Hydroxyl Proton Molecule An oxygen atom has how many protons?1 6 16 2 8 NaOH (sodium hydroxide) will dissolve in water because it is…1 postive alkaline polar negative How many protons does a hydrogen atom have?1 2 8 0 1 The oxygen atom of the water molecule has a slightly negative charge to it.1 True False What causes salt to dissolve in water?1 The fact that salt is an unstable crystal. The pull of the water molecules' postive and negative charges. The temperature of the water. The presence of ions in the water. When a molecule has one side that is more negative and one side that is more positive, we say that the atom is…1 an ion radioactive covalent polar Water molecules can break apart into and H+ and an OH-. What is the OH- part called?1 hydrogen ion hydronium ion hydroxide ion Why does the “ear” side of the water molecule have a positive electrical charge?1 Because the hydrogens don't have any neutrons. Because the hydrogen atoms don't get the shared electrons very often. Because the hydrogens are far away from the oxygen's nucleus. Because the electrons spend more time around the hydrogens than anywhere else. The Periodic Table is a complete list of all known…1 periods chemicals elements molecules 2: Carbon atoms and fatty acids Back to: 1: The water molecule
