how much energy is required to ionise a H atom if the electron occupies n = 5 orbit ? compare your answer with the ionization enthalpy of H atom (energy required to remove the electron from n - 1 orbit)

he uptake of drugs from the intestine is often strongly influenced by diffusion. for example, consider a water-insoluble steroid for treating inflammation that is solubilized in aggregates of detergent molecules, called micelles. these micelles, aggregates of 80 soap molecules, have a molecular weight of 24,000, a diameter of 2.6 nm, and a charge of -27. the positively charge ions (counterions) in this system are na".
