A: There are various causes of identity crisis, including improper upbringing, lack of affirmation and unpleasant past experiences. Other factors that lead to identity crisis include stress, troubles and societal demands. Lack of ideologies and values, experimenting roles and being a leader may also cause identity crisis.
The Periodic table can also be divided into several families of elements each having similar properties. For our purposes we will define the following ten families: Alkali metals. The alkali metals, found in group 1 of the periodic table, are highly reactive metals that do not occur freely in nature. These metals have only one electron in their outer shell. Therefore, they are ready to lose that one electron in ionic bonding with other elements.
Most of the elements are one kind or another of metal. Metals are those substances which have metallic properties like conductivity, hardness, conductor of heat and current ge â¦ nerally, posses some shearing strength, has some specific spring constant etc. how ever there are exceptions of these properties.his means that Lithium is the least reactive of the Group 1 elements and Francium the most reactive. Francium is radioactive and does not exist in large quantities, so practically caesium is the most reactive. Lithium, when placed on the surface of some water fizzes vigorously.
