Chemical bonds and properties of water

• Water is a polar molecule that forms hydrogen bonds with other water molecules.
• Water chemistry includes cohesion, adhesion, hydrogen bonding, and water's ability to dissolve hydrophilic molecules.
• Water repels hydrophobic molecules, causing nonpolar molecules to clump together.
• Solid water is less dense than liquid water due to hydrogen bonds.
• Cations are positively charged ions, and anions are negatively charged ions.
• Molecule is a group of atoms bonded together in a stable association
• Ionic bonds are the attraction of atoms with opposite charges (NaCl)
• Covalent bonds are where atoms are shared.
• Polar bonds are where high electronegative atoms bind with low electronegative atoms
• Non-polar are 2 low electronegative atoms bonded together.
• Hydrogen bonds are weak and form between polar molecules.
• Cohesion is where water attaches to itself, it allows little critters to walk on water.
• Hydrophilic is water loving, polar, and charged.
• Hydrophobic is water hating, non polar, and non-charged.
