Argon has eight valence electrons. In a dot diagram there are eight dots located around an element in the cardinal directions. two dots to be in place of every direction packed tightly as if to make a box around the element. Another way of stating it is that two dots are at zero degrees, two at ninety, two at 180 degrees and two more at 270 degrees on the cartesian plane.

Argon has completely filled valence orbitals and hence is unreactive. Sodium has one valence electron. If sodium loses this electron it will attain the stable electron configuration of the nearest noble gas (argon) and hence is reactive.
They have the same electron configuration as argon, which means they are isoelectronic with argon.
The element argon (atomic number 18) has the electron configuration 1s22s22p63s23p6 which can be abbreviated [Ne] 3s23p6
The electron configuration, in standard form, is [Ne] 3s2 3p6
The electron configuration for argon is: 1s22s22p63s23p6

18Ar is a noble gas. Its electron configuration is 1s2 2s2 2p6 3s2 3p6.
Ar is Argon and Ar 4s1 is the short form of the electron configuration 1s2 2s2 2s6 3s2 3s6 4s1. It means add 4s1 to the electron configuration of Argon to get the electron configuration of potassium.

argon atom
Argon, being one of the noble gases, has a completely filled outer electron shell and thus has zero valency.
The electronic configuration of Argon (Ar) is - 8,8,8 because its in group 8 and is inert because it has a full octet. Happy to help ;)
