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.
