Is p-block elements important for NEET?
The p-Block Elements is an important topic of the NEET Exam.
Physical properties, chemical properties, Anomalous properties, Oxidation states and Some important compounds of the B, Al, C and Si are all significant topics.p-block elements are those in which the last electron occupies p-orbitals and are found in groups 13, 14, 15, 16, and 17 (except helium).
Because p-block orbitals can only hold a maximum of six electrons, p-block elements are classified into six groups.
What are transition and inner transition elements Class 12?
Ans : The transition elements are elements that fill the d orbitals (groups 3–11 on the periodic table), and the inner transition metals are elements that fill the f orbitals.
Ans : The inner transition elements are those in which the final electron reaches the f-orbital.
What are d-block elements short notes?
d-block elements are also called transition elements or transition metals because they exhibit transitional behaviour between s block and p block elements.
In d-block elements, the valence shell has a constant number of electrons, whereas the number of electrons in the penultimate shell goes on increasing.
