- Argon is represented with the symbol Ar and is the 18th element on the periodic table.
- It is an inert/noble gas.
- its electronic configuration is written as { Ne] 3s23p6
- According to the 2,8,8 rule, The first shell can have only two electrons, the second shell can hold up to eight and the third shell can hold up to 18 etc.
