Short: [Ne] 3s2 3p5
Long: 1s2 2s2 2p6 3s2 3p5
[Ne] 3s2 3p5 ----------------
It is the short hand of electron destribution (electron configuration). Constructed by putting the symbol of the noble gas in the period before the element in brackets and continuing the electron configuration from where the noble gas left off. For example: the noble gas distribution of Aluminum is [Ne] 3s2 3p 1
Nonmetals such as chlorine usually gain electrons when they form ions, and the ion has a larger radius than the atom. So, It loses an electron It's radii becomes larger :]
[Rn] 7s2 is the noble gas notation for radium. A link is provided to the Wikipedia article on radium.

Chlorine is a nonmetal. It is only one electron short of a noble gas electron configuration and is much more likely to abstract an electron from some other element than to donate one to some other element.
The electron configuration of uranium is (short): [Rn]5f36d17s2.

The electron configuration of sulfur (long) is: 1s22s22p63s23p4. The electron configuration of sulfur (short) is: [He]3s23p4.
it is only one electron short from obtaining the noble gas structure so it only tries to gain one and resists the rest

The electronic configuration of chlorine, Cl is [Ne] 3s2 3p5. The Cl atom needs to gain an electron to attain the stable octet structure or noble gas configuration. Thus it has a tendency to draw electrons toward itself (it has high electronegativity). Non-metallic elements are short of electrons and gain or share them from other elements through the different types of bonding.
