Question

What is the abbreviated electron configuration of iodine (I)?

Answer 1

Answer:

b) [Kr] 5s² 4d¹⁰ 5p⁵

Explanation:

Properties of iodine:

Iodine is present in group seventeen.

It is halogen element.

Its atomic mass is 127 amu.

Its atomic number is  53.

It is present in solid form.  

It is crystalline in nature.  

It is very corrosive and has pungent odor.  

It can not react with oxygen and nitrogen.  

Electronic configuration:

I₅₅ = 1s² 2s² 2p⁶  3s³ 3p⁶ 4s² 3d¹⁰ 4p⁶ 5s² 4d¹⁰ 5p⁵

Abbreviated electronic configuration:

I₅₅ = [Kr] 5s² 4d¹⁰ 5p⁵

Abbreviated electronic configuration is shortest electronic configuration by using the noble gases.
