How does Element "k"(atomic number 19) has an electronic configuration as 2,8,8,1 as the rule for the electronic configuration says that "The electrons will fill the inner shells before the outer shells. First electrons will fill the K-shell and then L shell and so on. Thus, electronic configuration of elements follows an ascending order". The maximum number of electrons in the third shell is 32. How does it then start filling the 4th shell. Please explain

This is because it have capacity of 32 but according to a law it cannot took more than 8 applicable to shell l m and n

But how does then element "Sc" has electronic configurtion of 2,8,9,1??
Sorry 2,8,9,2
it is a d block element which have exceptionally differet properties
it is a d block element which have exceptionally different properties
ohh thank you
like their atomic size upto middle in series decreases but then increases
hmm
