Question

the period with electron in the Shell k l m

Answer 1

K is consist of two electrons and second shell is L consist of 8 electrons and third Shell is composed 18 electrons

Answer 2

the period with electron in the shell k,l,m because there is orbit and each orbit contain equal electron so first orbit taken "k" and number of electron is 2 , second orbit taken "l" and number of electron is 8 and third orbit taken "m" and number of electron is 18 so period of electron in the shell of k,l,m
