Sir question number 2 I think answer is 3 Lanthanum is often not considered a typical f-block element because, despite being part of the lanthanide series, it does not follow the same pattern of electron configuration as the other lanthanides. Here's why: 1. Electron Configuration: Lanthanum (atomic number 57) has the electron configuration [Xe] 5s² 4d¹ 5p¹. It does not start filling the 4f orbitals like the other lanthanides (which start from Cerium, atomic number 58). In the case of lanthanum, the 4f orbitals remain empty, and instead, the 5d orbitals are involved in bonding. 2. Position in the Periodic Table: Lanthanum is placed in the d-block of the periodic table due to its electron configuration. The f-block elements typically have electrons in the 4f or 5f orbitals, whereas lanthanum's electrons are in the 5d orbital. 3. Chemical Behavior: Lanthanum exhibits chemical properties similar to those of the transition metals (d-block elements) rather than the other lanthanides, which are more defined by the f-orbital electrons. For these reasons, although lanthanum is often grouped with the lanthanides, it is technically considered a d-block element rather than a true f-block element.

Sir notes kab tak milenge Hindi me?

Sir himdi me classes chahiye...app me English me hai vedeos

Pgt physics Ka notes banbayo please
