what does the arrangement of an atom and the bonds between them reflect about a mineral?
the way a mineral breaks, how hard it is, and what types of crystal shape it has
what are all the ways to identify minerals?
luster , streak, cleavage, fracture, atomic arrangement, hardness, crystal shape
what are two types of luster?
metallic and nonmetallic
is a naturally occurring inorganic solid with a crystalline form
mineral
the color of a mineral in powdered form
streak
when a mineral breaks along preferred planes of weakness creating sets of smooth parallel sides
cleavage
minerals that break with irregular surfaces exhibit
fracture
the physical property that measures a mineral’s resistance to scratching
hardness
molten rock material inside Earth
magma
how does metallic luster reflect light?
very easily, like a metal surface
how does nonmetallic luster reflect light?
how do you perform a streak test?
