Francium, Fr.
The element that completes the 7s sublevel is radium, with the electron configuration 7s2.
The element with its outermost electron in the 7s1 orbital is francium (element 87). Its outermost electron is in the 7th energy level (n=7), specifically in the 7s subshell.
The electron configuration of hassium is: [Rn]5f14.6d6.7s2.
The electron configuration for hassium (Hs) is [Rn]5f146d67s2.
The electron configuration of curium is [Rn]5f7.6d1.7s2.
The element that completes the 7s sublevel is radium, with the electron configuration 7s2.
The element with its outermost electron in the 7s1 orbital is francium (element 87). Its outermost electron is in the 7th energy level (n=7), specifically in the 7s subshell.
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.
The electron configuration of hassium is: [Rn]5f14.6d6.7s2.
The noble gas configuration for element 117 (Tennessine) is [Rn] 5f^14 6d^10 7s^2 7p^5. This means it has the same electron configuration as Radon up to its 5f electron level, followed by the filling of the 6d and 7s orbitals, and finally with 7p orbitals.
The electron configuration of rutherfordium is: [Rn] 5f14 6d2 7s2.
This would be a rather large electron configuration with somehwere around 27 valence electrons.... its kind of like playing with fire stating these facts though since this elements has been discovered but not fully confirmed.
The electron configuration for hassium (Hs) is [Rn]5f146d67s2.
The highest energy electron in uranium is found in the 5f subshell. Uranium has 92 electrons, so the configuration for the highest energy electron would be [Rn] 5f³ 6d¹ 7s².
The electron configuration of curium is [Rn]5f7.6d1.7s2.
A cesium atom has 1 valence electron. It is an alkali metal, and all alkali metals have 1 valence electron. The electron configuration for cesium is (Rn)7s1. The single electron in the 7s sublevel is its valence electron.
The electron configuration of einsteinium is [Rn]5f11.7s2.
