Question

In the three different Lewis dot structures shown below, the dots around each atom represent

• A. Total number electrons of the atom.
• B. Valence electrons of the atom.
• C. Bonded electrons.
• D. Atomic number.

Answer 1

The correct option is B Valence electrons of the atom.

In the Lewis dot structure, only the electrons of the outermost shell, i.e., valence electrons are depicted.

From the structure of the given elements, its evident that N
nitrogen has 5 valence electrons, ​​​​​​oxygen has 6 valence electrons and fluorine has 7 valence electrons.

Hence, we can say only valence electrons are represented in Lewis dot structure of an atom.
