So far, experiments have been conducted to attempt the synthesis of the next member of the group, '''[[unbinilium]] (Ubn)''', but these have all met with failure. However, since unbinilium is the second [[period 8 element]] and only the second element on the periodic table that has not been discovered yet, it is likely to be discovered in the near future.
 It is also possible that '''[[ununhexium]] (Uuh)''', which has been synthesised in [[2002]], is the next alkaline earth metal.

Like other groups, the members of this family show patterns in its electron configuration, especially the outermost shells resulting in trends in chemical behavior:

== Beryllium ==
As mentioned earlier, Be is “special”; it behaves differently. If the Be<sup>2+</sup> ion did exist, it would polarize electron clouds that are near it very strongly and would cause extensive [[orbital overlap]], since Be has a high charge density. All compounds that include Be have a covalent bond. Even the compound BeF<sub>2</sub>
  , which is the most ionic Be compound, has a low melting point and a low electrical conductivity when melted.
