Thanks a lot for helping
If valency is plus 2 then how ZnO why not ZnO2 by criss cross method, worry its silly but confusing...

formula of zinc oxide = ZnO
Valence shell contains 2 electrons that is 4s2 that means that zinc can lose the two electrons located in the 4s-orbital to be become the Zn2+ cation. So, the valency of Zinc is 2.
