PT Groups, Valence Electrons, Ionic Bonding Quiz
DIRECTIONS:
TAKE YOUR TIME AND READ THE QUESTIONS SLOWELY. If you have a question, don’t
hesitate to raise your hand and ask for help. I might not be able to give you the answer your looking
for but it never hurts to ask. MAKE SURE THAT YOU RECORD THE VERSION NUMBER IN THE
UPPER LEFT HAND CORNER OF THE QUIZ ON YOUR SCANTRON IN THE BOX THAT SAYS
“FORM”. DO NO WRITE ON THIS QUIZ. MARK A FOR TRUE AND B FOR FALSE.
