Lanthanides Series(f-Block Elements)-Definition, Configuration, Properties, Lanthanide Contraction, Oxidation State, Chemical Reactivity, Formation of Coloured Ions

September 5, 2025December 27, 2024 by Neeraj Anand, Param Anand
Lanthanides are the contemporary periodic table’s rare earth elements, with atomic numbers ranging from 58 to 71 after lanthanum. Rare earth metals are so-called because these elements are extremely rare (3 × 10-4 % of the earth’s crust). As lanthanide orthophosphates, they are accessible in ‘monazite’ sand.

P Block Elements MCQ Questions – Practice Questions of P Block Elements MCQ Chemistry with Answer & Explanations

September 5, 2025December 27, 2024 by Neeraj Anand, Param Anand
The elements of group 13 to group 18 in the periodic table are collectively called p block elements. They are called p block elements because the last valence electron enters the p atomic orbital. For example, the electron configuration of boron is 1s2 2s2 2p1. The last electron has entered the p subshell. The p block elements consist of boron family, carbon family, nitrogen family, oxygen family, halogen family and the noble gases.

Group 18(Noble or Inert Gas Elements)-Characteristics, Physical & Chemical Properties, Trends, Characteristics, FAQs

September 2, 2025December 26, 2024 by Neeraj Anand, Param Anand
Noble gases have eight electrons in their outermost orbit (except helium which has two electrons). As a result, they have a stable configuration. Group 18 elements are gases that are chemically unreactive, meaning they do not form many compounds. Be a result, the elements are referred to as inert gases. Noble gas elements, like the other group elements, display trends in their physical and chemical properties.  the noble gas family’s general configuration is ns2 np6 (except helium which has 1s2).
