Class 12

The Periodic Table’s s-block elements are those in which the last electron reaches the outermost s-orbital. Because the s-orbital can only hold two electrons, the s-block on the Periodic Table is separated into two groups (1 & 2). Periodic Group 1 of the Periodic Table comprises the elements lithium, sodium, potassium, rubidium, caesium, and francium.

The d-block occupies the larger middle section flanked by the s-block and p-block. The lattice structures of transition elements are formed by the repetition of unit cells. The lattice structure of transition elements or metals has closely packed and highly symmetrical structures such as body-centred cubic, face-centred cubic and hexagonal close packing.  The properties of

The d-block is found at the centre of the periodic table. It contains elements of the 3-12 group. Here, the d orbitals get filled in each of the four long periods. The f-block, on the other hand, is found at the bottom of the periodic table. It includes elements in which the 4 f and

D-block elements are those that have an incompletely filled d-subshell in their lowest energy state or most stable oxidation state. They are also known as transition elements. The (n-1) d subshell is included in the partially filled subshells. In the farthest shell, all d-block elements have about the same number of electrons. As a result,

The d-block occupies the larger middle section flanked by s-block and p-block. Lattice structures of transition elements are formed by the repetition of unit cells. The lattice structure of transition elements or metals has closed-packed and highly symmetrical structures such as body-centered cubic, face-centered cubic, and hexagonal close packing.
