Answer #1

Tungsten oxide:

A) W+4   O-2

B) W4   O2

C) Cris-cross the valencies:

we get: W2 O4

Hence the formula is : WO2

Lewis structure is: W is in VIB group, it has 6 valence electrons.

O has 6 valence electrons,it is in VIA group.

Total number of valence electrons = 6+6+6=18 electrons.

Now draw a skeleton:

O-W-O to make this skeleton 4 electrons are used up.

Remaining 14 electrons arrange in such a way that all the atoms should get octets.
