WebAnswer (1 of 2): Period-wise, the elements are most stable in the center and the least stable at the ends. On the lefthand side, the elements are unstable because they are looking to become cations (atoms that have lost electrons). On the righthand side, the elements are unstable because they are... WebAnswer (1 of 3): Reactivity of group II metals increases the further down the group, as it does with group one metals. This can be explained by the fact that group II metals form ionic bonds with chlorine- a halogen. The larger the atom, the further down the group, the larger the atomic radius, a...
