WebApr 6, 2024 · a) Maximum covalency of four: The first member of each group has 4 orbitals in the valence shell for bonding and hence can accommodate at the maximum 4 pairs or 8 electrons. These elements show a maximum covalency of four. Elements of 3rd period of p-block elements have vacant 3d orbitals lying between 3p and 4s level of energy. WebGenerally, the electronic configuration of these elements is (n−1)d 1−10ns 1−2. The (n–1) remains for the inward d orbitals which may have one to ten electrons and the peripheral …

WebApr 11, 2024 · 58-71 atomic numbers belong to the first series of the f-block i.e., the lanthanides. Lanthanides start from Lanthanum and the last lanthanide is Lutetium. But, similar to Actinium, Lanthanum (atomic no. 57) is not included in the f-block and belongs to the group 3. Hence, the f-block lanthanides are from atomic number 58-71.
