Why is H²O harmless, but H²O²(hydrogen peroxide) very lethal? How does the addition of a single oxygen atom bring such a huge change?

“2” should go in the subscript, not the superscript

Regarding the question, what describes how substances behave chemically isn’t the nuclei but the electrons. The oxygen atoms in water and in peroxide have the same nuclei, but the different structure of the molecules (specifically, there being an O-O bond in the peroxide) leads to the electrons being distributed differently, hence the chemical properties of the molecules are quite different
