The electron configuration of francium is: [Rn]7s1.
The abbreviated electron configuration of lithium is [He] 2s1.
The abbreviated electron configuration for argon is [Ne] 3s^2 3p^6. The [Ne] represents the electron configuration of the noble gas neon, which has the same electron configuration as the inner electrons of argon.
The noble gas configuration for francium (Fr) is [Rn]7s1, where [Rn] represents the electron configuration of the noble gas radon. Francium has 87 electrons, with the last electron occupying the 7s orbital.
The abbreviated electron configuration of oxygen is [He] 2s^2 2p^4.
The abbreviated electron configuration of cobalt is [Ar] 3d7 4s2.

[Kr]
The electron configuration of nobelium is [Rn]5f14.7s2.
7s1 because the definition of valence electrons are the outermost s and p electrons therefore in this case there is only an outermost s electron and therefore the answer is 7s1. NOTE:IT DOES NOT INCLUDE THE D AND THE F ELECTRONS!!!!Other valence configuration examples include;Nitrogen : 2s2 2p3Chlorine : 3s2 2p5Zinc: 4s2Bromine: 4s2 4p5
The noble gas configuration of francium is [Rn]7s^1, where [Rn] represents the electron configuration of radon, a noble gas element. Francium has one valence electron in the 7s orbital, making it highly reactive.
