In a Lewis symbol, where are the dots placed around the element's symbol?

• Only on the left side

• In a fixed position for each element

• Around the symbol in pairs, until all valence electrons are represented

• Randomly, as long as the correct number of dots is shown

What is the significance of the arrangement of dots in a Lewis symbol?

• It indicates the element's atomic mass.

• It shows possible bonding sites around an atom.

• It represents the number of protons in the nucleus.

• It is purely aesthetic and has no chemical significance.
