covalent bond
draw the electron dot structure of SiO2
Silicon has 4 valence electrons and Oxygen has 6.
Put the atom with the lowest # of valence electrons in the middle (in this case Si)
O Si O
Then start by making a single bond between each of the atoms then progress onto the double bonds if necessary until u have 8 electrons around each of the atoms
O = Si = O you should have 4 electrons (2 lone pairs for each of the oxygen atoms and none for the silicon
so there are 2 double bonds between Si and O (see above)
hope this helps;-D
