The electron configuration of plutonium is:
1s22s22p63s23p63d104s24p64d105s25p64f145d106s26p65f66d07s2
1s2,2s2,2p6,3s2,3p6,3d5,4s1
The electron configuration 1s22s22p63s23p64s23d5 is for manganese. Not 3d !
The electron configuration of uranium is: 1s22s2p63s2p6d104s2p6d10f145s2p6d10f36s2p6d17s2
The short electron configuration of plutonium is [Rn]5f67s2.
The noble gas configuration of plutonium is [Rn] 5f6 7s2. This configuration represents the electron arrangement of plutonium in a stable state, similar to a noble gas element, in this case radon.
The longhand electron configuration for sulfur is 1s2.2s2.2p6.3s2.3p4.
The electron configuration of beryllium is 1s22s2.
1s2,2s2,2p6,3s2,3p6,3d5,4s1
The electron configuration 1s22s22p63s23p64s23d5 is for manganese. Not 3d !
The electron configuration of sulfur (long) is: 1s22s22p63s23p4. The electron configuration of sulfur (short) is: [He]3s23p4.
The electron configuration of uranium is: 1s22s2p63s2p6d104s2p6d10f145s2p6d10f36s2p6d17s2
The electron configuration of plutonium is: [Rn]5f67s2.
The short electron configuration of plutonium is [Rn]5f67s2.
The noble gas configuration of plutonium is [Rn] 5f6 7s2. This configuration represents the electron arrangement of plutonium in a stable state, similar to a noble gas element, in this case radon.
[Rn] 5f6 7s2.
The longhand electron configuration for sulfur is 1s2.2s2.2p6.3s2.3p4.
Plutonium is a block f, period 7 actinide. Its electron configuration is 1s2 2s2 2p6 3s2 3p6 3d10 4s2 4p6 5s2 4d10 5p6 4f14 5d10 6s2 6p6 5f6 7s2. A shorter way to write this is as [Rn] 5f6 7s2 since the beginning of this electron configuration is the same as the noble gas, radon's.
