I was given a graph of square of the wave function of a hydrogen atom, against the distance of the electron from the nucleus (denoted by r).
What I know is that the square of the wave function gives the probability of finding an electron at a particular position, but could anyone explain to me that why does the area under this graph has to do with the probablity of locating an electron? Because I thought that on the graph where the highest value of square of wave function is, the corresponding value of r will be the answer. Isn't that so??
