this is because the atomic no of Potassium is 19 and the rule says the last electrons will be not more than the 8 and if the no. of electrons are more 8 then it will be written in the form of 8,8 or the last electronic configuration will be the last shell's electron.

Wrong
It will be 2,8,18,32,32,6,2.
no
the formula is 2n²
it will be like 2,8,18,32,32,8
No
The Fermium has atomic number 100
it comes in 7th row
Your answer 2,8,18,32,32,8 is of 6 numbers
This element should have 7 shells

The electronic configuration of potassium is 2,8,8,1 .
This is because the potassium comes in 4th row.
The electronic configuration of an element also depends upon , to which row does the element belongs.
Potassium is in 4th row , So its atom will distribute in 4 shells.
