Capitolo 10, Problema 37d
Write the Lewis symbol for each atom or ion. d. Cl-
Guida verificata passo dopo passo1
Understand that a Lewis symbol represents the valence electrons of an atom or ion using dots around the element's symbol.
Identify the element: Cl (Chlorine).
Determine the number of valence electrons for a neutral chlorine atom, which is 7, as chlorine is in Group 17 of the periodic table.
Recognize that Cl- is a chloride ion, which means it has gained one additional electron, making the total number of valence electrons 8.
Draw the Lewis symbol by placing 8 dots around the Cl symbol, representing the 8 valence electrons of the chloride ion.

Ecco i concetti essenziali che devi comprendere per rispondere correttamente alla domanda.
Lewis Symbols
Lewis symbols, also known as Lewis dot diagrams, represent the valence electrons of an atom or ion. Each dot corresponds to a valence electron, and they are placed around the chemical symbol of the element. This visual representation helps in understanding bonding and the reactivity of elements.

Lewis Dot Symbols
Chlorine Atom and Ion
Chlorine (Cl) is a halogen with seven valence electrons in its outer shell. When it gains an electron to form the chloride ion (Cl⁻), it achieves a stable octet configuration, resulting in a total of eight valence electrons. This change is crucial for understanding its chemical behavior and bonding.

Ionic Charge Representation
The ionic charge of an atom or ion is indicated by a superscript next to its chemical symbol. For example, Cl⁻ indicates that the chlorine atom has gained one electron, resulting in a negative charge. This notation is essential for accurately representing the electronic structure and stability of ions.
