Question

multiple - choice question
what noble gas would be used for the noble gas configuration for chlorine?
neon
argon
helium
krypton

Explanation:

Chlorine has 17 electrons. Neon has 10 electrons. The noble - gas configuration of chlorine starts with the electron configuration of neon and then adds the remaining electrons in the outer - shells. Argon has 18 electrons, helium has 2 electrons, and krypton has 36 electrons, which are not the appropriate starting points for chlorine's noble - gas configuration.

Answer:

A. neon
