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.
Bromine is a very reactive element. While it is less reactive than fluorine or chlorine, it is more reactive than iodine. It reacts with many metals, sometimes very vigorously. For instance, with potassium, it reacts explosively. Bromine even combines with relatively unreactive metals, such as platinum and palladium.romine is too reactive to exist as a free element in nature. Instead, it occurs in compounds, the most common of which are sodium bromide (NaBr) and potassium bromide (KBr). These compounds are found in seawater and underground salt beds. These salt beds were formed in regions where oceans once covered the land.
