1s2 2s2 2p6 3s1
There are 11 electrons orbiting around the nucleus of Na. The Last one (3s1) is the valance Electron.
The long hand electron configuration of manganese is: 1s22s22p63s23p64s23d5.
The electron configuration for nitrogen is written as 1s2 2s2 2p3.
The electron configuration of zirconium is: [Kr]5s24d2
It is [Ne] 3S2.
[Kr] 5s2
The shorthand electron configuration of magnesium is [Ne]3s2.
The long hand electron configuration of manganese is: 1s22s22p63s23p64s23d5.
The electron configuration for nitrogen is written as 1s2 2s2 2p3.
The electron configuration of zirconium is: [Kr]5s24d2
It is [Ne] 3S2.
[Kr] 5s2
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.
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 element with this electron configuration is manganese (Mn), which has 25 electrons.
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.
The ground-state electron configuration for a neutral atom of manganese is: 1s22s22p63s23p63d54s2 or [Ar]3d54s2
Carbon has the chemical symbol of C and an atomic number of 6. Its shorthand or electron configuration is 1s2 2s2 2p2.
