notes Database for chapter The p Block Elements.
The p-Block Elements. General trends: 1. Valence shell electronic configuration : ns2 np1. 2. Atomic radius increases on moving down the group. Exception: The atomic radius of Ga is less than that of Al. This is because of poor shielding of d-electrons in Ga. 3. Ionisation enthalpy: Decreases (not smoothly) on moving down
Chapter 7: The p-Block Elements. Top Concepts. 1. p-Block elements: Elements belonging to groups 13 to 18 of the periodic table are called p-block elements. 2. General electronic configuration of p-block elements: The p- block elements are characterized by the ns2np1-6 valence shell electronic configuration. 3.
1. P-Block Elements. The nitrogen family is element group 15 of the periodic table. The nitrogen family consists of nitrogen phosphorus, arsenic, antimony and bismuth. Nitrogen family elements consists of atoms having 5 electrons in their outer energy level. A pnictogen is one of the chemical elements in group 15 of the
In Class XI, you have learnt that the p-block elements are placed in groups 13 to 18 of the periodic table. Their valence shell electronic configuration is ns2np1–6. (except He which has 1s2 configuration). The properties of p-block elements like that of others are greatly influenced by atomic sizes, ionisation enthalpy, electron.
The p-Block Elements and their Compounds – I. Notes. Chemistry of Elements. 21.1 Boron and Aluminium. Boron and aluminium are the first two members of Group 13 of the periodic table. Though the outermost electronic configurations of boron and aluminium are similar yet there is a big difference between the properties
