Verified step by step guidance1
Understand that Lewis dot structures are a way to represent atoms and molecules focusing on the electrons involved in bonding.
Recall that atoms have core electrons (inner electrons) and valence electrons (outermost electrons).
Recognize that Lewis dot structures specifically show the valence electrons because these are the electrons that participate in chemical bonding.
Note that protons and neutrons are subatomic particles located in the nucleus and are not represented in Lewis dot structures.
Therefore, the dots surrounding the chemical symbol in a Lewis dot structure represent the valence electrons of the atom.
