Silicon is just silicone and silicone dioxide is one part silicon to every two parts oxygen.
no
Yes.
No. Silicon dioxide is a major component of many minerals, and is abundant in most sand, but they are not the same thing.
No, smoky quartz and moonstone are not the same thing. Smoky quartz is a silicon dioxide crystal while moonstone is a sodium potassium aluminium silicate.
SiO2--silicone dioxide, or silica. Interestingly, oxygen, and then silicone, are the two most abundant elements in the Earth's crust, with approximately 60.1% being oxygen and 20.1% being silicone.
The element, silicon, freezes (or melts - same thing) at 1414ºC / 2577ºF. This should not be confused with the commercial product "silicone", a polymeric rubber made from silicon. There are many different silicon polymers called silicone, but one popular type used for bakeware melts at about 1000ºF.
Sand is usually nearly pure silicon dioxide but may have other metal oxides also. The same is true for glass, but the fraction of material other than silicon dioxide is usually larger for glass. Neither of them is a pure compound; therefore neither of them has any exact chemical formula.
yes they are similar. silica is a form of slicon
They are the same substance.
No, Al2O3 is aluminum oxide, it occurs naturally as the mineral corundum. Silica is silicon dioxide or SiO2, it occurs naturally as the mineral quartz.
Onyx is silicon dioxide with some impurities.
Glass is almost completely made of silica (silicon dioxide), the naturally occurring form of the element silicon. This is basically the same substance as quartz and common sand. Silica is the most abundant substance on Earth and is paradoxically a liquid.
Opal is a form of silica, amorphous and hydrated: SiO2.nH2O.
Silica.
no "Silica, also known as silicon dioxide, is a compound made out of the two most abundant elements in the Earth's crust, silicon and oxygen (SiO2). Silica has three main crystalline varieties: quartz (by far the most abundant), tridymite, and cristobalite. Silica is the main constituent of more than 95 percent of rocks that comprise 59 percent of the earth's crust. Quartz makes up about 12 percent of the land surface and about 20 percent of the Earth's crust. The highest levels of silicon in humans are found in the skin and connective tissues. ....." and silica is the raw material for glass
No, potassium is an element and silicon dioxide is a compound that forms sand and glass.
No. Silicon dioxide is a major component of many minerals, and is abundant in most sand, but they are not the same thing.
No, smoky quartz and moonstone are not the same thing. Smoky quartz is a silicon dioxide crystal while moonstone is a sodium potassium aluminium silicate.
From Suite101, "Ordinary commercial glass is made from sand which is silica or silicon dioxide." Silica and silicon dioxide are more common than diamonds, and the structure of the atoms in glass is less stable and more absorbent than diamonds. (This mineral is also used in foodstuffs.) Diamonds are made from carbon. The carbon atoms bond to form diamonds more tightly than atoms of any other mineral. This makes diamonds the hardest mineral known. Light refracting from cut glass reflects and refracts at lesser intensities than diamond, because of the density and compactness of the carbon atoms as compared to the 'looser' silicon dioxide atoms.
