[Kr] 5s2
NO!!!! Each element has it own ground state electron configuration. Rubidium is [Kr] 5s1 Strontium is [Kr] 5s2. Notice that strontium has one MORE electron than Rubidium. The symbol [Kr] is shorthand for the full electron configuration of krypton.
[Kr]5s2
The electron configuration for nitrogen is written as 1s2 2s2 2p3.
The electron configuration of strontium is 1s22s22p63s23p63d104s24p65s2.
The electron configuration of zirconium is: [Kr]5s24d2
NO!!!! Each element has it own ground state electron configuration. Rubidium is [Kr] 5s1 Strontium is [Kr] 5s2. Notice that strontium has one MORE electron than Rubidium. The symbol [Kr] is shorthand for the full electron configuration of krypton.
The shorthand electron configuration of magnesium is [Ne]3s2.
[Kr]5s2
The electron configuration for nitrogen is written as 1s2 2s2 2p3.
The electron configuration of strontium is 1s22s22p63s23p63d104s24p65s2.
The electron configuration of zirconium is: [Kr]5s24d2
It is [Ne] 3S2.
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.
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.
Oh, isn't that just a happy little question! Strontium fluoride has the noble gas electron configuration of krypton, which is [Kr]. This means it has a stable electron configuration similar to a noble gas, making it less likely to react with other elements. Just like painting a serene landscape, understanding electron configurations can bring a sense of peace and harmony to your chemistry studies.
Carbon has the chemical symbol of C and an atomic number of 6. Its shorthand or electron configuration is 1s2 2s2 2p2.
