covalent
Silicon Dioxide.
SiO2 as it exists in linear and branched chains
Not hydride, but it is a mixture of covalent oxide and covalent silicate.Silt is made up of quartz (SiO2) and feldspar(KAlSi3O8 – NaAlSi3O8 – CaAl2Si2O8)
it's covalent cuz both Si and O are non-metals
covalent
Silicon Dioxide.
Discrete covalent molecules. eg CO2, N2,CH4. Covalent networks. eg SIO2

Usually, however, the are a few covalent compounds, such as silicon dioxide (SiO2) that form covalent networks rather than molecules.

ionic. Silicon is not a gas. Covalent compounds are made from gasses only.
No. Some compounds form covalent networks, in which each atom is colvalently bonded with at least 2 adjacent atoms. An example of a covalent network compound is silicon dioxide (SiO2), or silica. In SiO2 each silicon atom is bonded to four oxygen atoms and each oxygen atom is bonded to 2 silicon atoms.
SiO2, the clue is the 'di' suffix before the word oxide , meaning two.
SiO2 is covalent because the difference in electronegativity is not great enough for it to be considered ionic. Ionic compounds have a difference in electronegativity of greater than 1.9 The Answer above is not right. SiO2 is Covalent. correct, but ionic compounds have an electronegativity difference of 1.7 or higher, not 1.9.
Ionic bonds in compounds such as NaCl and covalent bonds in say diamond (C) and quartz (SiO2)
