i) Write the time-independent Scrödinger wave equation for helium (He) and H + 2 atoms. ii) If interactions between electrons are ignored in these equations, find the energy of the system in terms of electronvolt (eV). iii) Write the spin wave function of a system consisting of two electrons. iv) Specify how the angular momentum of an electron is defined according to classical mechanics, bohr atomic theory, and quantum mechanics, and the values it will take.
note: Please show all the steps and details carefully.
