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.
826 Views. Alkali metals are so reactive because of their low ionisation energy.It is the energy required to detach the outermost electron from an atom.And in usual reactions a metal loses its electron to form compound..5k Views. Alkali metals are known for being some of the most reactive metals. This is due in part to their larger atomic radii and low ionization energies. They tend to donate their electrons in reactions and often have an oxidation state of +1.
