Answer to Question #268650 in General Chemistry for mina

Question

give the ground state electron configuration and orbital diagram for chlorine(Z=17) and its anion formed when gaining one electron

Answer 1

The neutral atom chlorine (Z=17), for instance has 17 electrons. Therefore, its ground state electronic configuration can be written as 1s22s22p63s23p5. The chloride ion (Cl-), on the other hand, has an additional electron for a total of 18 electrons.
