All the alkali metals react with water, with the heavier alkali metals reacting more vigorously than the lighter ones. Source: Internet
An effect of the instability of an odd number of either type of nucleons is that odd-numbered elements, such as the alkali metals, tend to have fewer stable isotopes than even-numbered elements. Source: Internet
As with all alkali metals, lithium fires are difficult to extinguish, requiring dry powder fire extinguishers ( Class D type). Source: Internet
Atoms that are weakly electronegative (such as alkali metals ) have relatively few valence electrons that can easily be shared with atoms that are strongly electronegative. Source: Internet
As with oxides, protactinium forms mixed halides with alkali metals. Source: Internet
Because the superoxide releases the most energy when formed, the superoxide is preferentially formed for the larger alkali metals where the more complex anions are not polarised. Source: Internet
