Students in a science class prepared flashcards so that they could quiz one another about the arrangement of the Periodic Table. One of the flash cards contained information about two elements, Element L and Element M.
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?
three hydrogen (H)
one sulfur (S)
four oxygen (O)
Fe + O2 -> Fe2O3
