B
Ni2Cl
C
NiCl2
D
Ni2Cl3
Verified step by step guidance1
Identify the charge on the nickel ion in nickel(II) chloride. The (II) indicates that nickel has a +2 charge, so the ion is Ni^{2+}.
Determine the charge on the chloride ion. Chloride is a halide ion with a charge of -1, so the ion is Cl^{-}.
To form a neutral compound, the total positive charge must balance the total negative charge. Since Ni^{2+} has a +2 charge, you need two Cl^{-} ions to balance it out.
Write the chemical formula by combining one Ni^{2+} ion with two Cl^{-} ions, resulting in NiCl_{2}.
Verify that the formula is electrically neutral: (+2) + 2 imes (-1) = 0, confirming that NiCl_{2} is the correct formula.
