What are PDF block elements?
The elements constituting the f- block are those in which the 4f and 5f are progressively in the later two long periods; these elements are formal members of group 3 from which they have been taken outto form separate f-block of the periodic table.
What are the important topics in P block elements?
Atomic & ionic radii, Ionization enthalpy, Electronegativity, Melting and boiling point, Electron Donor or Acceptor Properties and many other physical properties of p block elements.
What groups belong to p-block?
The p-block contains groups 13, 14, 15, 16, 17, and 18, with the exception of Helium. (Helium is part of the s block.) The principal quantum number “n” fills the p orbital. There is a maximum of six electrons that can occupy the p orbital.
How do I download Vedantu notes?
These notes are available to download for free. On the vedantu website, select study material. Then choose the CBSE board option. Under that, choose the CBSE revision notes.
What is the other name of p-block element?
s-block and p-block elements are collectively called normal or representative elements (except zero group elements). Each period ends with a member of zero group (18th group), i.e., a noble gas with a closed shell ns2np6configuration.
Who discovered p-block elements?
Gallium (Ga; Mendeleev’s eka-aluminum) was discovered in 1875 by the French chemist Paul Émile Lecoq de Boisbaudran during a systematic search for Mendeleev’s “missing” element in group 13.
What are p block elements CBSE Class 12 chemistry?
CBSE Class 12 Chemistry Quick Revision Notes Chapter 7 The P-Block Elements The p-Block elements: Elements belonging to groups 13 to 18 of the periodic table are called p-block elements. General electronic configuration of p-block elements: The p-block elements are characterized by the ns2np1-6 valence shell electronic configuration.
What is covered in Class 12 chemistry Chapter 7 notes?
Plus, all associated pointers like their occurrence, electronic configuration, atomic radii, ionic radii, etc. are covered in Class 12 Chemistry Chapter 7 Notes. In the last portion of Class 12 Chemistry Chapter 7 Notes, all the details of group 17 elements (halogens) are provided.
How many groups of p-block elements are there?
Since a p-subshell has three degenerate p-orbitals each of which can accommodate two electrons therefore in all there are six groups of p-block elements. P block elements are shiny and usually a good conductor of electricity and heat as they have a tendency to lose an electron.
