This Progress Checkpoint is designed to see how well you understand molecules. You will get an opportunity to show how well you can model the bonding of different elements.
Ana, Isabella and Marcus are playing the “Guess Who” game. Marcus says he's thinking of a molecule that is made up of two elements.
He gives a clue saying there is 1 atom of “Element A” and 3 atoms of “Element X”.
He gives another clue saying both atoms are nonmetals.
His third and final clue is that the chemical formula should look something like:
AX3
Ana takes all 3 clues and says the molecule Marcus is thinking of is Ammonia (NH3).
Isabella takes all 3 clues and says the molecule Marcus is thinking of is Aluminum Fluoride (AlF3).
Draw (model) the correct molecule in the space provided.
Explain how your drawing shows which person is correct.
Marcus gave enough clues to correctly guess the molecule?
Who is correct?
