Question

What would be the name of Ni2O? What's the charges on each nickel cation? How does that translate into the name?

Answer 1

Name: Nickel (I) Oxide
Charge: +1
It provides the (I) to the name.

Explanation:

Since `Ni_2O` is an ionic compound, the first part of the name will be the name of the cation, Nickel. Since nickel is a transition metal, we must provide the oxidation state. Oxygen in ionic compounds usually exists in the -2 state, so nickel's charge will be `(+2)/(2 at\oms)=+1`. This is added in the middle part of the name. Finally, the last part of the name comes from the name of anionic oxygen, oxide.
