Exploring Periodic Trends in the Periodic Table

What does each block on the periodic table represent?

• A different compound

• A different isotope

• A different element

• A different molecule

What is indicated by the large letters on each block of the periodic table?

• The atomic number

• The atomic mass

• The atomic symbol

• The group number

What do the group numbers at the top of each column on the periodic table represent?

• Different periods

• Different families with similar atomic traits

• Different molecules

• Different isotopes

Which group contains the noble gases?

• The middle group

• The rightmost group

• The bottom group

• The leftmost group
