In the solid state it forms an fcc crystal with a melting point of -189.4 C and a boiling point of - 185.8 C. The electronic configuration of Argon is (Ne)(3s 2)(3p 6). Its atomic radius is 0.098 nm.

Writing out all the orbitals can be a bit laborious and so a frequent shorthand way is to write the electron configurations of potasisum and calcium as: [Ar] 4s 1 and [Ar] 4s 2 respectively, where [Ar ...

The sample is placed in a small chamber that is at a vacuum. Argon gas and an electric field cause an electron to be removed from the argon, making the atoms positively charged. The argon ions then ...
