Explain the difference in electron configurations between a neutral atom and its ion.
The ion has a different number of electrons compared to the neutral atom, affecting its electron configuration.
Explain the significance of dot diagrams in understanding chemical bonding.
Dot diagrams help visualize how atoms share or transfer valence electrons to form bonds.
