Quartz is the compound silicon dioxide (SiO2) and contains atoms of silicon and oxygen. It is usually clear.
Sulfur is a simple element composed of sulfur atoms. It is opaque and yellow.
Brimstone is an older name for sulfur, but it's the same! :)
A sulfur molecule is 2 sulfur atoms covalently bonded. A sulfur dioxide molecule is a sulfur atom and 2 oxygen atoms covalently bonded.
Sodium and sulfur are two distinct elements that are located in the third period in the periodic table. Sodium is a metal and sulfur is a non metal.
Quartz is much harder than calcite.
By deviding the mass by its volume.
Quartz is silicon dioxide (sand). Diamond is an allotropic form of carbon.
Quartz is a naturally occurring form of silica that often contains impurities.
Quartz movement is more traditional. Kintetic quartz relies on different principles and is a bit more accurate.
Brimstone is an older name for sulfur, but it's the same! :)
Sulfite is a ion, while Sulfur trioxide is a molecule
compacted
Both quartz and rock crystal are made up primarily of silicon dioxide. The main difference between them is that rock crystal does not have any significant amount of trace elements that would color it. Quartz does contain coloring trace elements.
The difference is in varying concentrations of quarts in each crystal.
A sulfur molecule is 2 sulfur atoms covalently bonded. A sulfur dioxide molecule is a sulfur atom and 2 oxygen atoms covalently bonded.
