The electron configuration of plutonium is: 1s22s22p63s23p63d104s24p64d105s25p64f145d106s26p65f66d07s2
The electron configuration 1s22s22p63s23p64s23d5 is for manganese. Not 3d !
The electron configuration of uranium is: 1s22s2p63s2p6d104s2p6d10f145s2p6d10f36s2p6d17s2
The noble gas configuration of chromium is [Ar] 3d5 4s1. It is written this way because the electron configuration of argon (1s2 2s2 2p6 3s2 3p6) is the closest noble gas configuration to chromium, with 3d5 4s1 representing the additional electrons in the chromium atom.
[Ar]3d54s1
The longhand electron configuration for sulfur is 1s2.2s2.2p6.3s2.3p4.
The electron configuration of beryllium is 1s22s2.
The electron configuration of plutonium is: 1s22s22p63s23p63d104s24p64d105s25p64f145d106s26p65f66d07s2
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 longhand (or full) electron configuration for xenon (Xe), which has an atomic number of 54, is 1s² 2s² 2p⁶ 3s² 3p⁶ 4s² 3d¹⁰ 4p⁶. This configuration indicates that xenon has a complete outer shell of electrons, making it a noble gas with low reactivity.
The electron configuration for Chromium (Cr) is [Ar] 3d^5 4s^1. The electron configuration for Chromium II (Cr^2+) is [Ar] 3d^4.
The noble gas configuration of chromium is [Ar] 3d5 4s1. It is written this way because the electron configuration of argon (1s2 2s2 2p6 3s2 3p6) is the closest noble gas configuration to chromium, with 3d5 4s1 representing the additional electrons in the chromium atom.
The electron configuration of a chromium atom is 1s2 2s2 2p6 3s2 3p6 4s1 3d5.
Chromium has 24 electrons. Its electron configuration is [Ar]3d5 4s1. This configuration allows for the half-filled d orbital, which gives chromium additional stability.
Chromium has atomic no. of 24. Its electronic configuration is 1s22s22p63s23p64s13d5 . It should be 4s23d4 but it is not because the half filled d-sub shell provides extra stability to chromium atom.
