Question

what does the electron - dot notation show? only the protons in an atom only the valence electrons in an atom only the neutrons in an atom all electrons in an atom

Explanation:

Electron - dot notation, also known as Lewis - dot structure, represents only the valence electrons of an atom. Valence electrons are involved in chemical bonding. Protons and neutrons are not shown in this notation, and it does not represent all electrons in an atom but just the outermost ones.

Answer:

Only the valence electrons in an atom
