Chapter 8: Problem 131
Some chemists think that helium should properly be called "helon." Why? What does the ending in helium (-ium) suggest?

Get started for freeList all the common ions of representative elements and transition metals that are isoelectronic with Ar.
Use your knowledge of thermochemistry to calculate the \(\Delta H\) for the following processes: (a) \(\mathrm{Cl}^{-}(g) \longrightarrow\) \(\mathrm{Cl}^{+}(g)+2 e^{-} ;(\mathrm{b}) \mathrm{K}^{+}(g)+2 e^{-} \longrightarrow \mathrm{K}^{-}(g)\)
The air in a manned spacecraft or submarine needs to be purified of exhaled carbon dioxide. Write equations for the reactions between carbon dioxide and (a) lithium oxide \(\left(\mathrm{Li}_{2} \mathrm{O}\right),\) (b) sodium peroxide \(\left(\mathrm{Na}_{2} \mathrm{O}_{2}\right),\) and \((\mathrm{c})\) potassium superoxide \(\left(\mathrm{KO}_{2}\right)\)
In general, atomic radius and ionization energy have opposite periodic trends. Why?
Most transition metal ions are colored. For example, a solution of \(\mathrm{CuSO}_{4}\) is blue. How would you show that the blue color is due to the hydrated \(\mathrm{Cu}^{2+}\) ions and not the \(\mathrm{SO}_{4}^{2-}\) ions?
