Consider an ion with the symbol Y³⁻ formed from a representative element. (6.1, 6.2, 6.3)b. What is the Lewis symbol of the element?

Ionic charge refers to the electrical charge an atom acquires when it gains or loses electrons. In this case, Y³⁻ indicates that the element has gained three electrons, resulting in a negative charge. Understanding how elements form ions is crucial for predicting their behavior in chemical reactions and their placement in the periodic table.

Lewis symbols, or Lewis dot structures, represent the valence electrons of an atom as dots around the element's symbol. This visual representation helps in understanding how atoms bond with each other. For an element that forms a Y³⁻ ion, the Lewis symbol will show the element's symbol surrounded by six dots, indicating the three additional electrons gained.

Representative elements are found in groups 1, 2, and 13-18 of the periodic table and include metals, nonmetals, and metalloids. These elements typically exhibit predictable behavior in terms of electron configuration and bonding. Recognizing that Y is a representative element helps in determining its Lewis symbol and understanding its ionic characteristics.
