    2. BDifferent forms of the same element which have the same number of protons and a same number of neutrons.
    3. CDifferent forms of the same element which have the different number of protons and a same number of neutrons.
  2. 2what is ionic bonding?
    1. Atransfer of electrons to form charged atoms
      Image for option A
    2. BSharing electrons to form a full outer shellImage for option B
  3. 3Ionic compounds have a regular lattice structure.
    1. ATrue
    2. BFalse
  4. 4Silver Chloride is soluble.
    1. ATrue
