Question

write the general outer electronic configuration ofs-,p-,d-,and f-block elements​

Answer 1

Answer:

The elements of Group 1 and Group 2 of the modern periodic table are called S block elements. The general outer electronic configuration of s block elements is ns(1-2).

P block elements are in which the last electron enters any of the three p-orbitals of their respective shells. The general electronic configuration of p-block elements is ns2np1-6 except for Helium (He).

D block elements are the elements which can be found from the third group to the twelfth group of the modern periodic table. The valence electrons of these elements fall under the d orbital. D block elements are also referred to as transition elements or transition metals. The general outer electronic configuration of d block elements is (n−1)d(1−10)ns(0−2).

Elements whose f orbital getting filled up by electrons are called f block elements. These elements have electrons, (1 to 14) in the f orbital, (0 to 1) in the d orbital of the penultimate energy level and in the outermost’s orbital. The general outer electronic configuration of f block elements is (n−2)f(0−14)(n−1)d(0−1)ns2.
