Francium!
The element with an outermost electron configuration of 6s2 is Barium (Ba). It is classified as an alkaline earth metal on the periodic table.
The element with the electron configuration Rn 7s1 is francium (Fr). It is in period 7, group 1 of the periodic table. Francium is a highly radioactive alkali metal with very limited practical applications due to its extreme rarity and radioactivity.
The electron configuration of francium is: [Rn]7s1.
There are 5 electrons in the outermost electron shell of a phosphorus atom. Phosphorus has the electron configuration 2-8-5, so it has 5 electrons in its outermost shell.
The electron configuration of Fr, or Francium starts with the base configuration of [Rn]. The outer shell is 7s1, giving 1 valence electron.
The element is francium.
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 element carbon
This is a chemical element. You can find the how many electron in a single atom by using a periodic table.
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.
