,a solid mixture of one or more metals, sometimes also containing one or more nonmetals -
Answer -alloy
electrons can be readily promoted to the conduction band, where they are free to move
through the substance - Answer -conductor
the energy gap between the valence band and the conduction band is so large that electrons
cannot be promoted into the conduction band - Answer -insulator
substances that normally are not conductors but will conduct electricity at elevated
temperatures or when combined with a small amount of certain other elements - Answer -
semiconductor
most reactive metals, oxidation state of +1 - Answer -alkali metals
somewhat less reactive than alkali metals, oxidation state of +2 - Answer -alkaline earth metals
- Answer -elemental N (N2) contains a triple bond and is very stable

contains both carboxyl group and amino group - Answer -amino acid
polymers of sugars - Answer -Polysaccharides
Amount of area exposed for the reaction of a solid. - Answer -Surface area impacts rate of
reaction how?
increase the # of reactants in the container, more collisions occur w/enough energy & proper
orientation. - Answer -Concentration impacts rate of reaction how?
