Question

comment on the electonegativity character of p-block elements

Answer 1

electrons are arranged in the shells of atoms around the nucleus. These shells are arranged according to their energy and can be represented as K, L, M, and N... The atomic shells can be further classified as s, p, d and f sub-shells. Each sub-shell is divided into orbitals which are denoted as s, p, d, and f-orbitals. The long form of the periodic table is also based in these orbital and sub-shells.


The periodic table can be divided into blocks; s, p, d and f according to their valence shell electronic configuration. The elements of s-block have their valence electron in s-sub shell. A first and second group of the periodic table is part of s-block. From the 3rd group, the valence electrons are filled in d-sub shell therefore, these elements are part of d-block and continue till 12th group of the periodic table. Form 13th group, again valence electrons are again filled in p-sub shell, therefore these elements are known as p-block elements. p-block elements are placed from 13th to 18th group of the periodic table. They include metals, non-metals and metalloids. This block is better explained group wise and each group is known for its 1st element such as carbon family, nitrogen family, boron family etc. Let’s have a look at some more features of p-block of elements.
