Question

ccc patterns when asked why a chlorine atom gains one electron to form an anion with a 1 - charge, a classmate answered, “because noble gas configurations are stable.” is this statement generally true? explain.

Explanation:

Chlorine has 7 valence electrons. Gaining one electron gives it an electron configuration like argon (a noble gas). Noble gas electron configurations are stable because the outermost energy level is full. This makes the atom less likely to react. So, the statement is generally true as atoms often gain or lose electrons to achieve a stable noble - gas - like electron configuration.

Answer:

The statement is generally true. Chlorine gains an electron to achieve a noble - gas (argon - like) electron configuration, which is stable due to a full outer energy level.
