Question

In the Lewis dot structures for the three different elements given below, the dots around each symbol represent the _______ of the elements.

• A. total number of electrons
• B. valence electrons
• C. bonded electrons
• D. atomic number

Answer 1

The correct option is B valence electrons

In Lewis structures, the nucleus and the inner shell electrons are represented by the symbol of the element. While, the valence electrons are represented as dots around the symbol of the element.

Therefore, every dot in all the given Lewis symbols represents the number of valence electrons present in each of the given elements.
