There are three main regions of the periodic table. Choose one element from each of these regions and list the following for all three of them: a) it's symbol and the region to which it belongs b) the period and group number in which it resides c) it's atomic number Example: (Do not use these elements as your examples!) • Aluminum (Al) is an element located in the metal region of the periodic table in Group 3A, Period 3. It's atomic number is 13. . Bromine (Br) is an element located in the nonmetal region of the periodic table in Group 8A, Period 4. It's atomic number is 35. Antimony (Sb) is an element located in the metalloid region of the periodic table in Group 5A, Period 5. It's atomic number is 51.

How do binary compounds with hydrogen illustrate the concept of periodicity?
2.84 Early attempts to arrange the elements often focused on atomic weight. Mendeleev considered a number of properties in addition to atomic weight, so he realized that some elements seemed out of place when ordered by atomic weight. Using the modern periodic table, identify elements for which Mendeleev must have had to switch the order in order to get the correct sequence of elements.
2.42 What is a period in the periodic table? From what does it derive its name?
What is the name of the element in Group 4A and Period 5?
2.26 In what region of the periodic table are you likely to find elements that form more than one stable ion?
Classify the following as metals, nonmetals, or metalloids: a.argon b.element 3 c.Ge d.boron e.Pm
One of the best indications of a useful theory is that it raises more questions for further experimentation than it originally answered. How does this apply to Dalton’s atomic theory? Give examples.
What defines an element? How many naturally occurring elements exist?
Distinguish between the terms family and period in connection with the periodic table. For which of these terms is the term group also used?
One of the early models of the atom proposed that atoms were wispy balls of positive charge with the electrons evenly distributed throughout. What would you expect to observe if you conducted Rutherfords experiment and the atom had this structure?
What is meant by stating that the charge of an electron is 1? What is the symbol of the electron?
The symbols for most elements are based on the first few letters of the respective element’s common English name. In some cases, however, the symbol seems to have nothing to do with the element’s common name. Give three examples of elements whose symbols are not directly derived from the element’s common English name.
