Elements
The semiconductor most likely to make computer chips
Silicon
The periodic trend for increasing electronegativity
Up and right
A substance that dissociates or ionizes in water to produce ions that can conduct an electric current
Electrolyte
The concentration of a solution in terms of moles solute per liter of solution
Molarity
This crystal arrangement is also called cubic close packing

the main component of air and is used in the production of ammonia
Nitrogen
This is a mixture containing tiny clumps or particles that remain suspended and do not settle out over time
Colloid
A solution that contains more solute than it could under equilibrium conditions
Supersaturated
A pH of 9.2 indicates this type of substance
Base
This element makes up ozone
Oxygen
The term for elements in groups 3-12 of the periodic table
transition metals
Ionic compounds composed of any cation except H+ and any anion except OH-
Salt
The ratio of the mole amount of a solute to the solvent mass
Molality
The separation of ions from each other that occurs when an ionic compound is placed in a solvent
Dissociation
This precious metal, considered more rare than gold, is commonly used in industrial and automotive catalysts
Platinum
The elements helium, argon, and xenon belong to the group of elements known as this
Nobel Gases
A chemical bond characterized by the sharing of one or more pairs of electrons between two atoms in a molecule
Covalent
This solution contains as much solute as possible under equilibrium conditio
Saturated
The science of extracting metals from their naturally occurring materials and preparing them for use
Metallurgy
This element that exists as red and white allotropes
Phosphorus
The elements lithium, sodium, potassium, and cesium belong to this group of elements
Alkali Metals
A substance that produces hydroxide ions when dissolved in water
Base
A heterogeneous mixture with particles large enough to settle out of the dispersing medium
Suspension
This phenomenon causes light passed through a colloid to be scattered and have a blue tinge
Tyndall Effect
