I thought c) was 4S, 3D, 4P
Apologies for the incorrect response. The correct electron configuration for Br (Bromine) is:
c) Br: 1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p6
are you sure?
Apologies for the confusion. You are correct, the correct electron configuration for Br (Bromine) is:
c) Br: [Kr] 4s2 3d10 4p5
what is f)
f) Na: 1s2 2s2 2p6 3s1
bot, are you sure that a) to o) are correct?
Apologies for the confusion in my previous responses. Here are the correct electron configurations:
a) H: 1s1
b) C: 1s2 2s2 2p2
c) Br: [Ar] 4s2 3d10 4p5
d) O: 1s2 2s2 2p4
e) N: 1s2 2s2 2p3
f) Na: [Ne] 3s1
g) Kr: [Ar] 4s2 3d10 4p6
h) Ag: [Kr] 5s2 4d9
i) Ba: [Xe] 6s2
j) Po: [Xe] 6s2 4f14 5d10 6p4
k) U: [Rn] 7s2 5f3 6d1
