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 francium is: [Rn]7s1.
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 electron configuration of Fr, or Francium starts with the base configuration of [Rn]. The outer shell is 7s1, giving 1 valence electron.
Electronic configuration of hafnium: [Xe].4f14.5d2.6s2
The element is francium.
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.
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 electron configuration of francium is [Rn]7s1.

The electron configuration of francium is: [Rn]7s1.
The electron configuration of francium is [Rn]7s1.
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.

You can buy several SACd players ranging from the reasonably priced Sony's SCD-CE595 to the outrageously priced Marantz SA 7S1.The latter may cost more than your car is worth.
