8 Ionic compounds have high melting points because:  A.    They are strong conductors of electricity. B.    Their crystal lattice energy is high and therefore making it difficult to collapse the solid structure. C.    They possess charges that are difficult to disperse on heating  D.    Heat can not penetrate them properly while inside capillary tubes 9 Credits to its discovery goes to James Chadwick, after Schrodinger developed his atomic model: a.    Neutron  b.    Nucleus  c.    Alpha particles d.    Photons  10 What would happen to an atom in its grounds state if external energy was applied to the electrons? a.    Electrons move to an orbital further away from the nucleus b.    Atom would be destroyed c.    Electrons would be destroyed d.    Nucleus becomes supercharged and absorbs the electron.
