Which set of elements has a strong tendency to form cations? Or which of the elements are the most electropositive elements?

The elements belonging to Group 1 and group 2 of periodic table has the strong tendency to form cations. The reason behind this tendency is that the elements belonging to group 1 and 2 have one and two valance electrons respectively. By loosing the valence electrons, they will aquire noble gas configuration. It is easy to release 1 and 2 […]

The ionic bonds are not limited to one ion only, actually they keep on joining again and again because they are held together by basically the electrostatic forces, due to the oppositely charged ions. lets take example of NaCl molecule.
