How can you determine the group valence of an element based on Lewis symbols?

Options

  1. ABy counting the number of protons
  2. BBy adding the number of valence electrons and inner shell electrons
  3. CBy subtracting the atomic number from the number of dots
  4. DBy either counting the number of dots or calculating 8 minus the number of dots

Correct answer

D. By either counting the number of dots or calculating 8 minus the number of dots

Step-by-step solution

The group valence of an element can be determined either by counting the number of dots (valence electrons) or by calculating 8 minus the number of dots.
