Since Calcium oxide is a neutral compound so the charge on Oxygen should be -2. Valency of Oxygen is 2, so a single Oxygen atom can satisfy the need. Therefore formula is CaO.
destroyer1654:
oxygen valency two
then its sum will be - 1
2 hydrogen share one electron each and one oxygen share 2 electrons with each of hydrogen atoms
it is not an ionic bond
it is formed by covalent bonding
I understood there are 2+ hydrogen valency and - 2 valency of oxide
therefore neutral
us be Brailist now
congrats
shut up all
