Use the second period of the periodic table as an example to show that the size of atoms decreases as we move from left to right. Explain the trend.
Predict the atomic number and ground-state electron configuration of the next member of the alkali metals after francium.
(a) The formula of the simplest hydrocarbon is \(\mathrm{CH}_{4}\) (methane). Predict the formulas of the simplest compounds formed between hydrogen and the following elements: silicon, germanium, tin, and lead. (b) Sodium hydride (NaH) is an ionic compound. Would you expect rubidium hydride (RbH) to be more or less ionic than NaH? (c) Predict the reaction between radium (Ra) and water. (d) When exposed to air, aluminum forms a tenacious oxide \(\left(\mathrm{Al}_{2} \mathrm{O}_{3}\right)\) coating that protects the metal from corrosion. Which metal in Group 2 A would you expect to exhibit similar properties? 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?
Predict the products of the following oxides with water: \(\mathrm{Na}_{2} \mathrm{O}, \mathrm{BaO}, \mathrm{CO}_{2}, \mathrm{~N}_{2} \mathrm{O}_{5}, \mathrm{P}_{4} \mathrm{O}_{10}, \mathrm{SO}_{3} .\) Write an equation for each of the reactions. Specify whether the oxides are acidic, basic, or amphoteric.
