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).
What is the force of repulsion at this same separation distance?show all work step by step problems formula
