WebAug 29, 2024 · The wave function Ψ is a mathematical expression. It carries crucial information about the electron it is associated with: from the wave function we obtain the electron’s energy, angular momentum, and orbital orientation in the shape of the quantum numbers n, l, and ml . The wave function can have a positive or negative sign. WebFeb 6, 2014 · Feb 6, 2014 Ground state energy not only can be negative, it is negative. Explanation: The energy of an electron is zero when the electron has completely left the atom, i.e., when its principal quantum number n = ∞. When the electron is bound to the atom with any closer value of n, its energy is lower and is therefore negative.

WebNov 8, 2024 · The left side of this equation is strictly positive, while we are assuming the left side is negative, so this solution doesn't work. The problem with the plane wave is that two derivatives brings down the imaginary i twice, changing the sign.
