Bonding Chemical Bond- attraction between two or more atoms forming a compound. .
Ionic Bond- Transfer of electrons • Ions- Positively or negatively charged atoms in an ionic bond
Hydrogen Bond • Attraction between a hydrogen atom with a positive charge and another atom with a negative charge.
SPECIAL PROPERTIES OF WATER • Holds Energy- absorbs and holds large amounts of heat. • Examples- • Ocean/pool takes long time to heat and long time to cool • Sweating- helps maintain internal temperature • Thunderstorms
Expansion- expands as it freezes. Solid form is less dense than liquid- ice floats.
Adhesion & Cohesion- attraction between particles allowing it to stick to itself and other particles. This allows for water movement in plants.
Adhesion • Attraction between molecules of different substances. • Ex…. Water and glass= Meniscus
Cohesion • An attraction between molecules of the same substance.
