Chlorine is a highly reactive liquid, while argon is an inert gas. Explain this

Question

Chlorine is a highly reactive liquid, while argon is an inert gas. Explain this difference based on their electron configurations. Which is the largest atom in group 4A? Which atom has a charge of +3 and an electron configuration of [Ar]3d^3? Draw the Lewis structures for the following compounds. C_6H_12; PCl_5 NH_3 HCN Describe the Octet Rule in your own words. Define electronegativity. Describe the trend of electronegativity across the periodic table. How does electronegativity influence bond polarity?

Explanation / Answer

11) The difference can be explained on the basis of the electronic configuration of both .

Chlorine -  [Ne] 3s23p5

Argon -  [Ne] 3s23p6

As it is clearly seen from the electronic configuration that chlorine need one electron to complete its octet so it has very high tendency to react with the compounds .On the other hand, argon has its filled octet so it behaves as an inert compound.Also, the size increases in the end of the period so it exists as gas .

12) Flerovium

13) The atom is chromium
