4. students in a science class prepared flash cards so they could quiz one another
about the arrangement of the periodic table. one of the flashcards contained
information about two elements, element l and element m.
atoms of element m have two more
valence electrons than atoms of element l
• atoms of element l are more reactive than
atoms of element m.
• both elements are metals.
the students had to use the information on the flash card to determine possible
positions of the two elements on a blank periodic table. which periodic table has
the elements placed in locations that match the information on the flash card?
