THE p -BLOCK ELEMENTS - NCERT
www.ncert.nic.inTHE p-BLOCK ELEMENTS In p-block elements the last electron enters the outermost p orbital. As we know that the number of p orbitals is three and, therefore, the maximum number of electrons that can be accommodated in a set of p orbitals is six. Consequently there are six groups of p–block elements in the periodic table numbering from 13 to 18.

apsmeerut.comBoiling point: PH 3 < AsH 3 < NH 3 < SbH 3 < BiH 3 Boiling point increases with increase in size due to increase in van der Waals forces. Boiling point of NH 3 is more because of hydrogen bonding. Bond angle: NH 3 (107.8°) > PH 3 (99.5°) > AsH 3 (91.8°) ≈ SbH 3 (91.3°) > BiH 3 (90°) Electronegativity of N is highest. Therefore, the lone ...
