[Kr]5s2
[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.
The electron configuration for nitrogen is written as 1s2 2s2 2p3.
The noble gas configuration for Sr (strontium) is [Kr]5s2
The shorthand configuration of radon is [Xe] 4f^14 5d^10 6s^2 6p^6.
[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.
The shorthand electron configuration of magnesium is [Ne]3s2.
The electron configuration for nitrogen is written as 1s2 2s2 2p3.
The noble gas configuration of strontium is [Kr]5s². Strontium has an atomic number of 38, which means it has 38 electrons. The noble gas before strontium is krypton ([Kr]), which has 36 electrons. The remaining two electrons fill the 5s orbital in strontium, leading to the noble gas configuration [Kr]5s².
[He]2S1
The noble gas configuration for Sr (strontium) is [Kr]5s2
The shorthand configuration of radon is [Xe] 4f^14 5d^10 6s^2 6p^6.
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.
