Because both silicon and oxygen 'share' electrons. As the oxidation state of Si is +4 and Oxyen is -2
4-2-2=0
So the sharing of the electrons in the atoms forms a stable molecule.
And a covalent bond is the name for the sharing of electrons in a bond.

Not sure what that means... but both silicon dioxide (sand) and diamond are covalent networks.

Silicon dioxide has a network covalent bonding.
a covalent bond
Covalent bond.
Carbon dioxide is a molecular covalent bond, as no metals are present in the gas.
Silicon Dioxide.
It is Aluminium combined with Silicon, and it's bond is covalent.
Because silicon is a metalloid/semi-metal and carbon is a nonmetal, the bond is covalent.
