Silicon dioxide is a molecule made of one silicon and two oxygen for a total of three atoms.
The molecular formula for silicon dioxide is SiO2, so there are a total of three atoms; one silicon atom, and two oxygen atoms.
Sand is silicon dioxide, formula SiO2
Well, honey, silicon dioxide, also known as silica, contains one silicon atom and two oxygen atoms per molecule. So, if we're talking about a single molecule of silicon dioxide, it contains a total of three atoms. But if you're asking about a sample of silicon dioxide, well, that could contain trillions upon trillions of atoms depending on the size of the sample. Hope that clears things up for ya, sugar!
The chemical formula of Silicon dioxide is SiO2. Two oxygen atoms are bond to a silicon atom. This compound has 3 atoms per molecule.
The compound silicon monoxide (SiO) has only two atoms; one silicon atom, one oxygen. The prefix "mono" tells you there is only one oxygen attached; "bi" or "di" (such as in silicon dioxide) would tell you there are two oxygens (for total of three, in that example).

Silicon dioxide is composed of silicon and oxygen atoms in a 1:2 ratio. It is a common mineral found in many forms, including quartz and sand.
Quartz consists of silicon and oxygen (2 times as many oxygen atoms than silicon atoms).
The structure of silicon dioxide consists of silicon atoms bonded to four oxygen atoms in a tetrahedral arrangement. These tetrahedra link together to form a three-dimensional network structure, resulting in a rigid and crystalline material. Silicon dioxide can exist in different forms such as quartz, amorphous silica, and glass, depending on the arrangement of its atomic structure.
Well take Si (as its own element, being silicon) and see how many atoms it has in that one unit, which would be 1 (notice that it has no number next to it) then see how many atoms are in the O2 (Oxygen) obviously it has 2 because of the number next to it. So you take the two numbers and add. 2+1=3. 3 atoms are present.
SiO2 is a macromolecule. Each silicon atom is covalently bonded to four oxygen atoms and each oxygen atom is covalently bonded to two silicon atoms.
3.10 moles SiO2 (1 mole Si/1 mole SiO2)(6.022 X 1023/1 mole Si) = 1.87 X 1024 atoms of silicon =====================
