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?

OlanmaE

Noble gases have the maximum number of electrons in their outer shell. The statement made by the student about the stability of noble gases is generally true.

  • It is true that noble gases are stable elements. This can be attributed to the fact that they have the complete number of elements in their outer shell. That is why they hardly participate in any reactions.

  • The chlorine atom receives an electron from a donor element and attains a negative charge.

  • When two chlorine atoms bond covalently, they share electrons and thus attain the noble state configuration.
