the statement can be made that atoms and molecules are always in motion. elaborate on the reason that liquids can exist.

a) activation energy is equivalent to allow the atoms to ionize and to migrate away from its nearest neighbors.
b) the internal energy of the atoms is inadequate and allows the atoms to break away completely from its nearest neighbors.
c) external energy output is strong enough to allow the atoms to withdraw bonding and disassociate from its nearest neighbors.
d) intermolecular forces are sufficient to keep the atoms closely packed but do not allow the atoms to disassociate from its neighbors.
