Atoms with greatly different electronegativity values are expected to form no bonds ionic bonds none of these covalent bonds triple bonds

Atoms with greatly different electronegativity values are expected to form ionic bonds 

1.from liquid state to gaseous state is evaporation 3.solid to liquid is melting 5. solid to gaseous state is sublimation 6. gas to solid state is decomposition 7. a change of state is known as the states of matters

The kinetic energy of the liquid increases. hope this !
