  • 3. 
    To form the salt calcium fluoride, calcium ____________ 2 electrons. (loses/gains)
  • 4. 
    At the same time, fluorine (F) ___________ electrons since it has 7 valence electrons and wants to grab one more to get the stable octet. (loses/gains)
  • 5. 
    Ca wants to give a way 2 electrons; meanwhile, F is only willing to accept one. As a result, Ca must give electrons to ____ fluorine atoms. (1 or 2 or 3)
