Electronic configuration: - Chlorine: [Ne]3s23p5 - Fluorine: 1s22s22p5
chlorine is a group seven element with outmost energy level lacking only one electron, thus is not stable. when it gains this electron, it gets an octet electron structure(8 e in the vallency shell) this makes it very stable in the enviroment; the reason why chlorine molecule exists due to its stable atoms but chlorine atom does not exist in nature

1s2 2s2 2p6 3s2 3p6 is the electron configuration of chlorine
Electronic configuration: - Chlorine: [Ne]3s23p5 - Fluorine: 1s22s22p5
Chlorine's structure makes it very reactive (it is in group VII of the Periodic Table and therefore needs to gain one electron in order to become stable)!
it is only one electron short from obtaining the noble gas structure so it only tries to gain one and resists the rest

The electron configuration for neutral Chlorine is 2.8.6.
1s2 2s2 2p6 3s2 3p6 is the electron configuration of chlorine
Chlorine attracts 1 electron
The electron configuration of chlorine is 1s2 2s2 2p6 3s2 3p5
The electron is transferred to chlorine.
== == The valency of an element is the measure of electrons it needs or needs to loose to obtain a stable structure (a noble gas structure, such as helium, neon, argon ...) for example in NaCl, sodium has 11 electrons which means 1 valence electron, chlorine has 17 electrons which means it has -1 valence electrons; so sodium looses 1 electron and chlorine gains that electron so sodium ends up with 10 electrons (Neon's electron structure) and chlorine ends up with 18 electrons (Argon's electron structure) the number of outer electrons. Noble elements are the most stable elements (thats why they don't react well and stay alone, like helium) so all the other elements try to obtain the noble electron structure. Elements usually gain or loose 4 electrons.
