How are Lewis dot diagrams used to represent ionic compounds?
Most of the time, the Lewis structure of the individual ions are ignored.

Lewis dot diagrams are used to represent ionic compounds by showing the transfer of electrons from one atom to another. Each atom's symbol is surrounded by dots representing valence electrons. For example, in sodium chloride (NaCl), sodium donates one electron to chlorine, forming Na+ and Cl- ions. In the Lewis dot diagram, Na is represented with one dot and Cl with seven dots.

In Lewis dot diagrams, the valence electrons of each atom are represented as dots around the symbol of the element. For ionic compounds, the transfer of electrons from one atom to another results in the formation of ions.
To represent an ionic compound using Lewis dot diagrams, you would first draw the Lewis dot diagrams for each element involved in the compound, showing the transfer of electrons. For example, in sodium chloride (NaCl), sodium (Na) transfers one electron to chlorine (Cl) to form Na+ and Cl- ions.
The Lewis dot diagram for Na would show one dot (representing the transferred electron) next to the Na symbol, and the Lewis dot diagram for Cl would show seven dots (representing its original seven valence electrons) and one cross (representing the electron it gains from Na) next to the Cl symbol.
In the final Lewis dot diagram for the ionic compound NaCl, you would show the Na+ ion next to the Cl- ion, indicating that they are held together by ionic bonds due to the attraction between the oppositely charged ions.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
