1. Brittle• Having little elasticity; hence easily
cracked, fractured, or snapped.

2. Conductivity• Property of metals and alloys that allows
heat or electrical charges to pass through the material easily.

4. Luster• Property of metals and alloys that describes
having a shiny appearance or reflecting light.

6. Malleable• Ability of metals and alloys to be rolled or
hammered into thin sheets.

7. Metal• Element that typically is a hard, shiny solid, is
malleable, and is a good conductor of heat and electricity.

8. Metalloid• Element that shares some properties with
metals and some with nonmetals.

9. Nonmetal• Element that usually is a gas or brittle solid at
room temperature, is not malleable or ductile, is a poor conductor of heat and electricity, and typically is not shiny.

10. Reactive• A chemical that, in the pure state, or as
produced or transported, will vigorously polymerize, decompose, condense, or become self-reactive under conditions of shock, high pressure, or high temperature.

11. Semiconductor• Materials having conductivity properties
between that of metals (good conductors) and nonmetals (insulators) and having controllable conductivity parameters.
Silicon Germanium

sound.
