1. Discuss why no single atom of potassium has a mass of 39.1u when the average atomic mass of potassium is 39.1u.
2. Is it possible to determine the percentage abundance of each isotope? Why or why not? Assume that an unknown element "X" exists naturally as three different isotopes. The average atomic mass of element X is known alone with the atomic mass of each isotope.
3. You know that silver exists as 2 isotopes: silver-109 and silver-107. However radio isotopes such as Silver -106, silver-105, silver-108 and the silver-110 to silver-117 are known. Why do you not use the abundance and mass of these isotopes when you determine the average atomic mass of silver?
4. Determine the differences between the alkenes and the multiple-bond compounds?
5. Find out possible reasons for the differences in boiling points between the compounds.
