Chem Review: Chapter 6

What is the purpose of the periodic table?

• Organization of elements
• Grouping by properties
• Organization of information
• All of these

4.a. Which of the following describes the organization and layout of Mendeleev's table?

• He was using mass to order the elements and gaps were left in the table for elements not yet discovered.
• He was using electron configuration to order the elements
• He was using atomic numbers to order the elements

4.b. How was the problem with Mendeleev's periodic table corrected?

• Using atomic numbers
• Using quantum numbers
• Using mass numbers
• Using valence electron numbers

• series
• groups
• families

Give TWO names for vertical columns in the periodic table. (Pick both correct answers.)

• periods
• series

Mercury (Hg) is . . .

• a transition metal that is liquid at room temperature.
• an inner transition metal that is liquid at room temperature.
