Which of the following is not true for the quantum mechanical model of the atom?
1 Even though there is one electron in a H-atom, there are many atomic orbitals in the atom as many wave functions are possible as the solution of the wave equation.
2 All the information about the electron in an atom is stored in its orbital wave function \(\psi \) and quantum mechanics makes it possible to extract this information out of \(\psi .\)
3 The probability of finding an electron at a point within an atom is proportional to the square of the orbital wave function i.e., \(|\psi {|^2}\) at that point.
4 \(|\psi {|^2}\) is known as the probability density and can never be positive.
