In quantum mechanics, the Hamiltonian operator describes the total sum of which property for a system?

Explanation:
The Hamiltonian in quantum mechanics is the energy operator for the system. In the usual non-relativistic form, it combines kinetic energy and potential energy, written as H = p^2/2m + V(x). This makes the Hamiltonian the generator of time evolution via the Schrödinger equation, iħ ∂ψ/∂t = Hψ, so its eigenvalues correspond to the possible total energy levels the system can have. It’s not a single property like mass, momentum, or charge, but rather the operator that encodes the total energy content of the state (including both motion and interactions through the potential).
