Cohesion and Adhesion

Cohesion

Attraction between particles of the same substance. Water and water both attract in the three different forms of mater.

Adhesion

Attraction between two different substances. Water and Oxygen both have adhesion

Ionic bond

a chemical bond between a metal cation and a nonmetal anion with opposite charges

Covalent Bond

a chemical bond that occurs between nonmetals by sharing electrons.

Surface tension

Tension of surface film of a liquid caused by attraction of particles.

Polarity

electrons to give a side a partial negative charge

Capillary action

result of adhesion

Hydrogen bond

weak chemical attraction between polar covalent molecules

Octet rule

when atoms have 8 electrons in outer layer
