Calculate the probability of finding an electron that is described by this wavefunction in a volume of 1.0 pm3 (i) centred on the nucleus, (ii) at the Bohr radius, (iii) at twice the Bohr radius. (c) Construct an expression for the radial distribution function of a hydrogenic 2s electron (see part (b) for the form of the orbital), and plot the function against r. What is the most probable radius at which the electron will be found? (d) For a more accurate determination of the most probable radius at which an electron will be found in an H2s orbital, differentiate the radial distribution function to find where it is a maximum.
Coal combustion can affect freshwater or marine (saltwater) organisms in different ways. Describe the steps involved in one such way, from combustion to the effect(s) on one species or group of organisms.
