Given,
An element has an atomic number of 11
To find,
The arrangement of electrons in the Shell
Solution,
Total number of electrons in the element = Atomic number = 11
The number of electrons in the first shell = 2
The number of electrons in the second shell = 8
The number of electrons in the third shell = 1
Hence, the arrangement of electrons in the shells is 2,8,1
