What happens to the atoms in a liquid as it freezes

When a liquid freezes:

• The particles still vibrate

• The particles move together into organised rows and columns into a fixed position

• And the density of the substance increases

an ion is a charged atom or molecule. it is charged because the number of electrons do not equal the number of protons in the atom or molecule. an atom can acquire a positive charge or a negative charge depending on whether the number of electrons in an atom is greater or less then the number of protons in the atom.
