Chemical Properties of Alkaline Earth Metals - As alkaline Earth metals have low ionization energies and high electropositive character, they are very reactive and have a strong tendency to lose valence electrons, though less than alkali metals. The reactivit..

As alkaline Earth metals have low ionization energies and high electropositive character, they are very reactive and have a strong tendency to lose valence electrons, though less than alkali metals. The reactivity of these elements increases on going down the group. The ch..

A magnetic compass was used to help the sailors for navigational purpose. But recently it has been discovered that some migrant birds have magnetic sensors in their heads, which help to guide them using the Earth's magnetic field. William Gilbert suggested that Earth itself is a..

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 alkali metals a..

Corrosive Action : Strong alkalis like sodium hydroxide and potassium hydroxide are highly corrosive or caustic in nature. Sodium hydroxide and potassium hydroxide are commonly called caustic soda and caustic potash respectively. Organic tissues like skin, etc. get completely corr..

Ethers are relatively inert compounds inspite of the presence of oxygen atom carrying two lone pairs of electrons in their molecules. These are not easily attacked by alkalis, dilute mineral acids, metallic sodium, PCl 5 etc. under ordinary conditions. It is because of this reason that th..

. solution of NaOH, glucose first turns yellow, then brown and finally resinifies. However, with dilute NaOH, glucose undergoes a reversible isomerisation and is converted into a mixture of D-glucose, D-maltose and D-fructose. This reaction is known as Lobry de Bruyn-van Ekenstein rearrangement. Sa..
