What occurs when an atom loses an electron?
However, if something happens to make an atom lose or gain an electron then the atom will no longer be neutral. An atom that gains or loses an electron becomes an ion. If it gains a negative electron, it becomes a negative ion. If it loses an electron it becomes a positive ion (see page 10 for more on ions).
What is the electron configuration of a chlorine atom in the excited state?
2-8-8
Is chlorine ground state or excited state?
(2) 2-8-6-1 this is the excited state of Chlorine, on the periodic table the ground state is 2-8-7. The excited state electron configuration is showing an electron leaving one energy level and moving up to a higher level.
What is the electron configuration of a neutral chlorine atom?
The neutral atom chlorine (Z=17), for instance has 17 electrons. Therefore, its ground state electronic configuration can be written as 1s22s22p63s23p5.
