tending to break rather than to flex or bend
what is brittle?
elements that are typically solid, shiny, malleable, and good conductors
what is metals?
to classify metals, nonmetals, and metalloids, you would look at these three physical properties
what is luster, conductivity, and malleability? (in any order)
the following is a property of a nonmetal:
- conducts electricity and heats well
- can be hammered into thin sheets
- is brittle and breaks easily
- has a shiny, metallic luster
what is brittle and breaks easily?
the best property to classify an unknown element as a metal, nonmetal or metalloid is-
what is conductivity?
a physical property that describes the ability of a substance to transfer heat or electrical energy
what is conductivity?
elements that are typically not shiny, not malleable, and poor conductors
what is nonmetal?
the way a surface appears when it reflects light is referred to as this property
what is luster?
To classify elements as metals, nonmetals, and metalloids, you would use the following properties except:
- texture
- conductivity
- luster
- malleability
what is texture?
what are conduct electricity and heat well, have a shiny luster, and be malleable?
elements that have properties of both metals and nonmetals
what is metalloids?
a physical property that describes the ability of a material to be permanently reshaped without breaking or cracking
what is malleability?
what is a poor conductor of electricity?
Iron is classified as a metal while Silicon is classified as a metalloid. These two elements could have these physical properties in common
what are luster and malleability?
what are metals are good conductors of electricity?
a substance whose electric conductivity falls between that of a conductor and an insulator
what is a semiconductor?
a physical property that describes the way the surface of the substance shines or reflects light
what is luster?
Elements from greatest conductivity to least conductivity are these three main groups
what are metals to metalloids to nonmetals?
Metals will have these common physical properties
what is shiny luster, malleable, and conducts electricity?
Between Cobalt, Arsenic, Hydrogen, and Carbon, this element most likely has a shiny luster
what is Cobalt?
a characteristic that can be observed or measured without changing the substance
what is physical property?
to sort or put into groups based on similar or dissimilar physical, chemical, or biological characteristics
what is classify?
