Two
Explanation:
Valence electron
Electron present in valence shell of an atom is called valence electron.
Valence shell
The valence shell is the outermost shell of an atom in its uncombined state, which contains the electrons most likely to account for the nature of any reactions involving the atom and of the bonding interactions it has with other atoms.
Outermost shell of Ni is 4th shell i.e N shell. It contains 2 electrons.
Therefore Ni has 2 valence electrons.
