Qu 2 Schematically plot attractive, repulsive, and net energies versus interatomic separation for two atoms or ions. Note on this plot the equilibrium separation (distance) ro and the bonding energy Eo.
Qu 3 How many atoms (or molecules) are in one mole of the substance?
Qu 4 Mole, in the context of this book, is taken in units of gram-mole. On this basis, how many atoms are there in a pound-mole of a substance?
Qu 5 The atomic radii of Mg* and F ions are 0.072 and 0.133 nm, respectively.
Calculate the force of attraction between these two ions at their equilibrium interionic separation (i.e., when the ions just touch one another).
