Question

Give an example to show that in neutral molecules, the algebraic sum of the oxidation number of all
the elements is zero.

Answer 1

Answer:

In a neutral molecule, the sum of the oxidation numbers of all atoms is zero. For example, in H2O, the oxidation numbers of H and O are +1 and −2, respectively. Because there are two hydrogen atoms in the formula, the sum of all the oxidation numbers in H2O is 2(+1)+1(−2)=0.
