Valence electrons in metallic bonding occupy whole piece of metal, they do not connected to particular atom,
in ionic they move to more electronegative atom, in covalent bond they between atoms ( covalent polar located closer to more electronegative)
Answer:
Change occur in heat energy.
Explanation:
Change occur in the heat energy of molecules during condensation process. The molecules of gas releases its heat energy and converted into liquid state. With this heat energy, they are active and escape from each other but when the heat energy is removed from them, the attractive forces between these gas molecules are formed which convert them into liquid state so change in heat energy occur in the condensation process.
Protons and neutrons have most of the mass but occupy very little of the volume of the atom.
