Interpretation: The number of valence electrons in a molecule of phosphoric acid needs to be determined.
Concept Introduction: The number of valence electrons in an atom is equal to the number of electrons present in the valence shell. For a molecule, the number of valence electrons can be calculated by taking the sum of valence electrons of each atom in the molecule.
Answer to Problem 2STP
Option (D)
Explanation of Solution
Reason for correct options:
The given molecule is phosphoric acid,
Thus, the total number of valence electrons in
The correct option is (D).
Reason for incorrect options:
The total number of valence electrons in a molecule is the sum of valence electrons of each atom present in the molecule. Since, after calculation, the total number of valence electrons comes out to be 32, options (A), (B), and (C) are incorrect options.
