The radii of the lithium and magnesium ions are 76 pm and 72 pm, respectively. Which compound has stronger ionic attractions, lithium oxide or magnesium oxide?
Even though several elements have only one naturally occurring isotope and atomic nuclei have whole numbers of protons and neutrons, no atomic mass is a whole number. Use the data from Table 2.2 to explain this fact.
Argon has three naturally occurring isotopes, 36Ar,38Ar, and
40Ar. What is the mass number of each? How many protons, neutrons, and electrons are present in each?
Zinc sulfide (ZnS) occurs in the zinc blend crystal structure.How many kilograms of Zn are in 3.82 kg of ZnS?
