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.
Silicon dioxide is SiO2 and contains 3 atoms.
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).
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.
Silicon (a metalloid) and oxygen (a nonmetal) are the two elements that compose silicon dioxide (SiO2).
Of a network of atoms.
One atom of silicon can be combined in a compound two atoms of oxygen, forming the compound silicon dioxide, SiO2.
Quartz is a compound, specifically silicon dioxide, and compounds do not have atomic numbers; only atoms do.
Silicon dioxide is a substance (chemical compound) consisting of one silicon atom and two oxygen atoms.
The chemical formula of Silicon dioxide is SiO2. Two oxygen atoms are bond to a silicon atom. This compound has 3 atoms per molecule.
Silicon dioxide is a chemical compound that is made from combining two oxygen atoms and one silicon atom. Under exposure to oxygen, a silicon surface oxidizes to form silicon dioxide (SiO2).
Silicon dioxide is SiO2 and contains 3 atoms.
Sand is silicon dioxide, formula SiO2
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).
One silicon atom = Si Two oxygen atoms = O2 Chemical formula for silicon dioxide compound = SiO2
Silicon dioxide is a molecule made of one silicon and two oxygen for a total of three atoms.
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.
No, a silicon dioxide molecule is composed of 1 silicon atom and 2 oxygen atoms.
