Metals, Nonmetals, and Metalloids Flashcards
Can be observed and measured without changing the composition of the matter.
Include: appearance, texture, color, odor, density, luster, conductivity, malleability, and ductility
Physical Properties
Refers to the way a metal’s surface reflects light. It can be shiny or dull
Luster
Refers to the way most metals can be stretched into wires
Ductile
Refers to the way most metals can be hammered or rolled into sheets
Malleability
Tendency of a material to fracture or fail with a small amount of force.
Examples: glass, silicon, chalk
Brittle
Measures the ease at which an electric charge or heat can pass through a material
Conductivity
Material that keeps energy such as electricity, heat or cold from easily transferring through
Insulator
Most abundant of the 3 types of elements, there are 88 of them on the periodic table
Metals
Shiny luster, good conductors, high density, high melting point, ductile, malleable
Physical Properties of Metals
This metal is commonly used for making coins and electrical wiring
Copper
This metal is commonly used for jewelry and dental fillings
Gold
This metal is commonly used for medicine and batteries
Lithium
This class of elements is normally found to the right of the stair step
Non Metals
This class of elements is found to the left of the stair step
Metals
This class of elements is along the stair step and is the smallest class.
Metalloids
No luster (dull), poor conductors, not ductile, not malleable, low density, low melting point
Non metals
This non metal supports life and is used in rocket fuel
Oxygen
This nonmetal is used to purify water and PVC pipes
Chlorine
This nonmetal is used in balloons and as coolant in MRI machines
Helium
Boron the moron is in what class of elements?
Metalloids
Solid, can be shiny or dull, ductile, malleable, semiconductors
Metalloids
This metalloid is present in heat resistant alloys, and the green color of fireworks
Boron
This metalloid is in glass and semiconductors
Silicon
This metalloid is a poison
Arsenic
