there is no shorthand configuration for helium. its electron configuration is 1s2
The shorthand configuration of radon is [Xe] 4f^14 5d^10 6s^2 6p^6.
[Kr]5s2
It is [Ne] 3S2.
[Kr] 5s2
The electron configuration for Hf using noble gas shorthand is [Xe] 6s2 4f14 5d2. The noble gas shorthand represents the electron configuration of the noble gas xenon, which has an electron configuration of 1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p6.
The shorthand electron configuration of magnesium is [Ne]3s2.
[He]2S1
The shorthand electron configuration allows all of the electrons in a noble gas preceding an element to be omitting and written by [nobel gas name]. For nitrogen, the noble gas preceding it is He. Thus, its configuration is [He]2s2 2p3.
The shorthand configuration of radon is [Xe] 4f^14 5d^10 6s^2 6p^6.
[Kr]5s2
Carbon has the chemical symbol of C and an atomic number of 6. Its shorthand or electron configuration is 1s2 2s2 2p2.
The shorthand electron configuration of aluminum is [Ne] 3s^2 3p^1, where [Ne] represents the electron configuration of the noble gas neon. This shorthand notation is used to show the core electrons before the valence electrons in the electronic configuration of an element.
google it
It is [Ne] 3S2.
[Kr] 5s2
2.3!<-----wrong shorthand electron configuration for Boron (B on the periodic table) is [He] 2s2 2p1 because Shorthand means building on the last noble gas element. So put the closest Noble gas element before this one and then the new addition.
[Ne]3s23p3
