Final answer:
The probability of finding an electron is highest at the location where the square of the electron wave function's amplitude is largest, which confirms the statement as true.
Step-by-step explanation:
The statement is true: the probability to find an electron trapped inside a ring of iron atoms on an atomically-flat copper surface is highest where the square of the amplitude of the electron wave function is largest. In quantum mechanics, the square of the wavefunction ψ at any point, which is ψ*ψ or | ψ |^2, represents the probability density of finding a particle, in this case, an electron, at that point in space. For an electron in an atom, this probability distribution can form complex shapes depending on the energy level and sublevel of the electron, but the principle remains: the denser the probability cloud, which is indicated by the density of colored dots on probability maps, the higher the likelihood of finding the electron in that region. The probability is never zero, even at great distances from the nucleus, but can be significantly lower.
