Why Nickel has this charge
Nickel is a transition metal. Transition metals can have multiple charges, so compound names and roman numerals matter.

Nickel oxide
Nickel can form oxides where total positive and negative charge balances.
FAQ
Is Nickel charge the same as oxidation state?
Ionic charge is the charge on an actual ion. Oxidation state is a bookkeeping number used inside compounds. They can match, but they are not always the same thing.
How do I use this in formulas?
Combine positive and negative ions so the total charge is zero. You can also use the ionic compound calculator.
Where can I see the full chart?
Use the periodic table with charges or the ionic charges chart.
