Which of these electron configurations are for atoms
in the ground state?In excited states?Which are impossible?
(a) 1s22s1,(b) 1s22s22p3,(c) [Ne] 3s23p34s1,(d) [Ne]
3s23p64s33d2,(e) [Ne] 3s23p64 f 4,(f) 1s22s22p43s2
(a) 1s22s1,ground
(b) 1s22s22p3,ground
(c) [Ne] 3s23p34s1,excited 3p34s1
(d) [Ne]3s23p64s33d2,impossible b/c 4s3
(e) [Ne] 3s23p64f4,excited,3p44f4
(f) 1s22s22p43s2,excited b/c 2p43s2请问您怎么判断的？如果回答的全面还给加分因为轨道是按这个顺序来的：1s, 2s, 2p, 3s, 3p, 3d, 4s, 4p, 4d, 4fground state, s orbital holds up to 2 electrons, p for 6, d for 10, and f for 14thus, 1s2,2s1 is ground state(c) [Ne] 3s23p34s1, is excited, since 3p3 is only half filled, not full, with 1e in 4s.(d) [Ne]3s23p64s33d2, is impossible b/c 4s3, since s orbital can't hold more than 2e.
