And Carbonate, which is a polyatomic ion.
And so, this indicates that I'm dealing with an ionic compound.
And so, I'm going to have to name it accordingly.
Now also notice that Nickel is a transition metal,
which means I have to indicate in the name what the charge is on the Nickel.
So let's look at first assigning the charge to the Nickel before we
write the name.
Now I know I have one Nickel ion with some charge that we're going to call x,.
Plus one Carbonate ion, and the charge on that is two minus.
Because this is a neutral compound,
the sum of those ionic charges should sum to zero.
And so I can actually just solve for x,
and find that the charge on the Nickel was going to be two plus.
Now, I can write the name of my compound.
And I'm going to say nickel.
