If the atomic weight of `Zn` in `70` and its atomic number in `30`, Then what be the atomic weight of `Zn^(2+)`?

Text Solution

Verified by Experts

In the formation of `Zn^(2+)` from Zn ,two electrons are removed .The number of proton and neutrons remain unchanged hence , the atomic weight of `Zn^(2+)` will be `70`
