Study Notes
p-Orbitals and Electron Accommodation
- A set of p orbitals can accommodate a maximum of 6 electrons.
Electronic Configuration of p-Block Elements
- The valence shell electronic configuration of p-block elements is ns² np¹ to ns² np⁶.
Influence of Inner Core on Element Properties
- The difference in the inner core of elements influences their properties due to the shielding effect, which affects the nuclear attraction on outer electrons.
Maximum Oxidation State of p-Block Elements
- The maximum oxidation state shown by a p-block element is +7, exhibited by chlorine (Cl).
Groups of p-Block Elements
- There are 6 groups of p-block elements in the periodic table, numbered from 13 (Boron group) to 18 (Noble gases).
Electronic Configuration of Boron in BF3
- The electronic configuration of boron in BF3 is 1s² 2s² 2p¹.
Electron Deficient Molecules and Lewis Acids
- Electron deficient molecules, like BF3, behave as Lewis acids, accepting electrons to form a coordinate covalent bond.
- This is because they have an incomplete octet and can accommodate additional electrons.
Tendency to Behave as Lewis Acids Down the Group
- The tendency to behave as Lewis acids decreases down the group due to the increase in size of the central atom, leading to a decrease in electronegativity and a decrease in the ability to form coordinate covalent bonds.
