Answer:
Outer most shell contain 8 electrons, so it is a noble gas..
E. C. = 2,8,8
It is Argon...
If we took in the form of shell, it's Electronic configuration is
1s2, 2s2, 2p6, 3s2, 3p6

The shells of an atom cannot accommodate more than 8 electrons, even if it has a capacity to accommodate more electrons. This is a very important rule called the Octet rule. According to this rule, atoms gain, loose or share electrons to achieve the stable configuration similar to the nearest noble gas.
E.C of Argon18 - 2,8,8.
1S2 2S2 2P6 3S2 3P6
Cl17 - 2,8,7.
1 S2 2S2 2P6 3S2 3P5
E.C of Argon18 - 2,8,8.
1S2 2S2 2P6 3S2 3P6
Cl17 - 2,8,7.
1 S2 2S2 2P6 3S2 3P5
