valence electrons

• positive ion

• electrons in the outermost shell

• the substance that is dissolved

cation

• the substance that is dissolved

• positive ion

• water fearing; having an aversion to water; tending to coalesce and form droplets in water

• Water is a polar molecule meaning it has opposite charges on opposite ends. This causes hydrogen bonds to form causing water to stick together.

anion

• negative ion

• two or more atoms held together by covalent bonds

• in a solution, the substance in which the solute dissolves.

• electrons in the outermost shell

solution

• the substance that is dissolved

• substance formed by the chemical combination of two or more elements in definite proportions

• the force that acts on the surface of a liquid and that tends to minimize the area of the surface

• a homogeneous mixture of two or more substances

solute

• water fearing; having an aversion to water; tending to coalesce and form droplets in water

• the substance that is dissolved

• smallest unit of life

• Anything that has mass and takes up space

hydrophobic

• two or more atoms held together by covalent bonds

• substance formed by the chemical combination of two or more elements in definite proportions

• water fearing; having an aversion to water; tending to coalesce and form droplets in water

• in a solution, the substance in which the solute dissolves.

polarity of water

• Water is a polar molecule meaning it has opposite charges on opposite ends. This causes hydrogen bonds to form causing water to stick together.

• two or more atoms held together by covalent bonds
