This energy overcomes the strong electrostatic forces of attraction which act in all directions between the oppositely charged ions: The strength of the ionic bonds depends on the charge on the ions.
The formula of an ionic compound can be deduced from the formulae of its ions. Remember that for the metal elements in groups 1, 2, and 3 the charge on the ion can be deduced by how many outer ...
However, a new study published in Physical Review Letters on October 22 has challenged the assumptions by providing direct evidence of the breakdown of spin statistics in ion-atom charge exchange ...
