Question

fracncium subshell elctronic configuration? ​

Answer 1

Answer:

Hydrogen, in the n=1 shell, has the simple electron configuration of 1s1 . Helium is 1s2 . The n=1 shell contains only the 1s subshell, containing one 1s orbital, which can hold a maximum of two electrons. ... Francium will fill orbitals all the way up to the 7s subshell, where it will have a half-filled orbital: 7s1
