Electron configuration for 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
Out of sodium potassium rubidium and cesium Which element has the greatest ionization energy?
Sodium has the greatest ionization energy of the four elements listed from column 1 of a wide form periodic table. Among this group of metals that readily form cations, the largest always has the lowest ionization energy and the smallest has the most. This is generally ascribed to the fact that the valence shell electron is further from the nucleus in the largest element and nearest in the smallest element.
What is the meaning of francium?
Fr is the symbol for the radioactive element francium.
Is francium a non polar solvent?
Francium is a chemical element, not a solvent.
What are some things that contains francium?
Francium is a true chemical element, not an example.
Which element has the smallest atomic radius rubidium cesium and francium?
Rubidium
Which element has one valenece electron?
Hydrogen, lithium, sodium, potassium, rubidium, cesium, and francium have one valence electron.
Which element has a low ionization energy?
Francium (Fr) has the lowest Ionization potential.
Which element had only one valance electron?
Hydrogen (H) Lithium (Li) Sodium (Na) Potassium (K) Rubidium (Rb) Cesium (Cs) Francium (Fr)
What element has its outermost electron is 7s1?
Francium!
Which element does the first 7s electron appear?
Francium, Fr.
which element has 3 fewer electrons than neon when neutral?
All the elements in the first column of the Periodic Table (lithium, sodium, potassium, rubidium, cesium, and francium) have one valence electron. I also believe Helium has one valence electron.
Which element in the periodic table has the smallest ionization enegry?
francium
What element has alkali metal?
No element has alkali metals. Some elements: lithium, sodium, potassium, rubidium, caesium and francium are akali metals.
What is the element that have few valence electron and give them easily?
First of all this is a lot more than just one element. All the alkali metals are like this, all having one valence electron. They are Hydrogen, Lithium, Sodium, Potassium, Rubidium, Cesium, and Francium. Yes they have elements named after countries.
What element contains 1 electron in its fifth energy level?
Rubidium
What family is the element Rubidium in?
It is a metallic element in the alkali family
