What is minerals good for?
It is good as it contains iron which is good for blood
What is the primary factor that determines whether an elements a metal or a nonmetal?
that metals are malleable, luster, and are good conducters
Are metals good conductors?
Yes. That is a characteristic of a metal.
Why is the rock granite a good example for the phrase minerals are the building blocks of rocks?
Granite contains many minerals and minerals are the 'true' building blocks of rocks
What elements have luster and are good conductors of heat and electricity?
Metals such as copper, silver, and gold have luster and are excellent conductors of heat and electricity due to the free movement of electrons within their atomic structure. These properties make them essential for various applications, such as in electrical wiring and circuitry.
Why isn't luster a good property to identify minerals?
Luster is not a good property for identifying minerals because many minerals look similar. Your best way of knowing which mineral is which is by measuring their hardness.
What are the characteristic metals?
They are good conductors of heat and electricity. They have a metallic luster. All are solids except mercury.
Which propety is generally the least useful when identifying minerals?
Color is generally the least useful property when identifying minerals, as many minerals can come in a variety of colors due to impurities in their composition. It is more reliable to rely on other properties like hardness, luster, cleavage, and streak for identification.
Do crystal forms provide a good reference for mineral identification?
Crystal forms and habits are one of the leading identifying characteristics of minerals.
Why is color not a good mineral property to use to identify minerals?
Color is not a reliable property because many minerals can occur in a variety of colors due to impurities or differing environmental conditions. It is common for two different minerals to share the same color, making it difficult to distinguish them based on color alone. Therefore, color is not a definitive characteristic and should be used in conjunction with other properties for accurate mineral identification.
Does limestone have luster?
Yes, limestone typically has a dull or earthy luster due to its high calcium carbonate content and fine-grained texture. It does not usually exhibit a shiny or reflective appearance like some other minerals or rocks.
Why is color not always a good way to identify minerals?
Color is not always a good way to identify minerals because some minerals change colors at certain temperatures. Some minerals have several colors and some are found in varied colors.
What is one property that may be used to distinguish metallic from nonmetallic minerals?
One property that can be used to distinguish metallic from nonmetallic minerals is luster. Metallic minerals have a shiny, reflective surface due to their high metal content, whereas nonmetallic minerals have a dull, earthy, or glassy appearance.
Rather than splitting apart evenly most minerals have a characteristic type of what?
Most minerals have a characteristic type of cleavage, which refers to the way they break along specific planes due to their internal atomic structure. Cleavage can be described as either perfect, good, or poor, depending on how easily the mineral breaks apart.
Why is color commonly unreliable property for identifying minerals?
Color can be unreliable for identifying minerals because many minerals can have the same color but different compositions. Some minerals can also come in a range of colors due to impurities or variations in their crystal structure. Therefore, it is better to rely on other physical properties, such as hardness, luster, cleavage, and specific gravity, for accurate mineral identification.
Is determination a characteristic?
yes. it is a good characteristic
Which class of elements has no luster and is a poor conductor?
non-metals mostly do not have the metallic luster and the electron clloud which leads to it and to good conductivity
