How do you determine the total number of electrons required for writing Lewis dot structures?

Options

  1. ABy counting the number of protons in the atoms
  2. BBy adding the valence electrons of the combining atoms
  3. CBy counting the number of neutrons in the atoms
  4. DBy adding the total number of electrons in the atoms

Correct answer

B. By adding the valence electrons of the combining atoms

Step-by-step solution

The total number of electrons required for writing the structures is obtained by adding the valence electrons of the combining atoms.
