1.	Amongthe elementsfrom atomicnumber1 to 36the number of elementswhich havean unpairedelectronin the s-subshellis
Answer» 4 7 6 9 Solution :Six elements have oneunpairedelectron in thes-subshell . THESEARE`._(1)H = 1s^(1), ._(3)Li= 2s^(1)` `._(11)Na = 3s^(1), ._(19) K= [Ar] 4S^(1), ._(24) Cr= [Ar] 3d^(5)4s^(1) ` and `._(29) Cu =[Ar]3d^(10)4s^(1)`
