Assign an oxidation state to each atom in each compound.
Oxidation state to each atom in each compound.
In NaCl the oxidation state of Na is +1 and oxidation state of Cl is -1
In NaCl , the o.s of Na is +1 and let the O.s of Cl is -1
1 + x =0
X= -1 (Cl)
In CaF2 , the oxidation state of Ca is +2 and F is -1.
