Alkali metals (Group 1 of the periodic table) and alkaline earth metals (Group 2 of the periodic table) are highly reactive towards air.
Alkali metals such as sodium, potassium, and lithium, react vigorously with air to form oxides. The reaction of alkali metals with air is exothermic, which means it releases a large amount of heat. When exposed to air, alkali metals become covered with a layer of oxide, which can sometimes even ignite due to the heat released during the reaction. Therefore, alkali metals are typically stored under oil to prevent them from reacting with air.
Alkaline earth metals such as magnesium and calcium also react with air, but not as vigorously as alkali metals. The reaction of alkaline earth metals with air is also exothermic, but less so than that of alkali metals. When exposed to air, alkaline earth metals also form oxides and are typically stored under oil to prevent them from reacting with air.
In summary, both alkali and alkaline earth metals are highly reactive towards air, with alkali metals being more reactive than alkaline earth metals. It is important to handle these metals with caution and to store them properly to prevent any accidental reactions with air.
What is Required s-Block Elements Alkali and Alkaline earth metals-reactivity towards air
The reactivity of alkali and alkaline earth metals towards air is a characteristic feature of the s-Block Elements in the periodic table. The s-Block Elements are a group of elements that have their outermost electrons in the s-orbital of their electronic configuration. This group includes the alkali metals and alkaline earth metals, as well as some other elements such as magnesium and aluminum.
The alkali metals, which include lithium, sodium, potassium, rubidium, cesium, and francium, are the most reactive of all the s-Block Elements. They react violently with air, water, and most other substances due to the low ionization energy of their outermost electron, which makes them very eager to lose this electron and form positively charged ions.
The alkaline earth metals, which include beryllium, magnesium, calcium, strontium, barium, and radium, are also quite reactive towards air, but less so than the alkali metals. This is due to their higher ionization energies, which make it more difficult for them to lose their outermost electrons and form positive ions.
The reactivity of the s-Block Elements towards air is important in a number of different contexts, such as the storage and handling of these elements in laboratory settings, and their use in industrial processes. It is important to be aware of the reactivity of these elements towards air, as it can have significant implications for their use and handling.

How is Required s-Block Elements Alkali and Alkaline earth metals-reactivity towards air
The reactivity of s-Block Elements, specifically the alkali metals and alkaline earth metals, towards air is a result of their low ionization energies. When these elements are exposed to air, the outermost electron in their valence shell can be easily removed, leading to the formation of positively charged ions.
Alkali metals such as lithium, sodium, and potassium, are highly reactive towards air and can ignite spontaneously in the presence of air. This is because they have a very low ionization energy and a strong affinity for oxygen. When exposed to air, they readily react with oxygen to form oxides, which can then react further with water vapor in the air to form hydroxides.
Alkaline earth metals, such as magnesium, calcium, and strontium, are also reactive towards air, but less so than alkali metals. This is due to their higher ionization energies, which makes it more difficult for them to lose their outermost electrons and form positive ions. However, they can still react with oxygen in the air to form oxides and other compounds.
The reactivity of s-Block Elements towards air has important implications for their use and handling in various applications. It is important to be aware of this reactivity in order to safely handle and store these elements in laboratory settings, as well as in industrial processes that involve their use.
Case Study on s-Block Elements Alkali and Alkaline earth metals-reactivity towards air
One real-world example of the reactivity of s-Block Elements, specifically the alkali and alkaline earth metals, towards air is in the production of magnesium alloys.
Magnesium is an abundant and lightweight metal with many desirable properties, such as high strength-to-weight ratio and good corrosion resistance. Magnesium alloys are used in a wide range of applications, including aerospace, automotive, and consumer electronics.
However, magnesium is highly reactive towards air and can easily ignite when exposed to oxygen, which can lead to fire and explosion hazards. This reactivity is due to the low ionization energy of magnesium, which makes it easy for the metal to lose electrons and form positive ions.
To address this reactivity, various measures are taken in the production of magnesium alloys. For example, the magnesium is often melted under a protective atmosphere of argon or other inert gases to prevent it from reacting with oxygen in the air. The alloys are also often coated with a protective layer to prevent corrosion and further reactions with air.
In addition, magnesium alloys may also be alloyed with other metals, such as aluminum and zinc, to improve their mechanical properties and reduce their reactivity towards air. These alloys are often used in applications where their low density and high strength are required, such as in the production of airplane parts and other lightweight structures.
In summary, the reactivity of s-Block Elements, specifically the alkali and alkaline earth metals, towards air has important implications for their use in various applications. The case study of magnesium alloys highlights the importance of understanding and addressing the reactivity of these elements in order to safely produce and use them in various industries.
