alkali metals list

Metals like zinc, lead and aluminium react with alkalis to yield salt and hydrogen. Remember : Hydrogen prepared by any of the above mentioned methods may contain impurities, and as a result may have a sm..

Alkali Metals - The six elements belonging to group 1 of the periodic table, namely lithium (Li), sodium (Na), potassium (K), rubidium (Rb), cesium (Cs) and francium (Fr) are called alkali metals. They constitute alkali metals because they..

Elements of group I A of the periodic table constitute a family of very reactive metals called alkali metals. They are lithium, sodium, potassium, rubidium, cesium and francium. All of them have one electron in the valence shell. They are called alkali ..

When ammonia is passed over heated sodium or potassium, amides are formed and hydrogen is set free. Alkali metal dissolved in liquid ammonia gives a blue solutions, which upon standing slowly, liberate hydrogen. The blue color of such solutions is due to the presence of sol..

Chemical Characteristics of Alkali Metals - Alkali metals exhibit a high chemical reactivity because of their low ionization energies low heat of atomization. Since the value of ionization energy decreases down the group (from Li to Cs) the reactivity of ..

Alkali metals exhibit a high chemical reactivity because of their low ionization energies low heat of atomization. Since the value of ionization energy decreases down the group (from Li to Cs) the reactivity of alkali metals increases from Li to Cs. All ..
