Which element is the largest K Rb Na Li?
Rb (rubidium) is the largest element among K (potassium), Rb (rubidium), Na (sodium), and Li (lithium). This is because as you move down a group in the periodic table, the atomic size increases due to the addition of more electron shells.
Which of these elements is the smallest element sodium potassium rubidium or cesium?
Of the Group 1 elements stated (Na, K, Rb, Cs), Caesium is the largest as it is the furthest down the group, and Sodium is the smallest of those as it is furthest up the group.
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?
Francium is a highly radioactive alkali metal element with the atomic number 87 and symbol Fr. It is the second rarest naturally occurring element in the Earth's crust and is extremely unstable, making it difficult to study. Francium was discovered in 1939 by Marguerite Perey.
Which element has the smallest atomic radius rubidium cesium and francium?
Francium has the largest atomic radius among rubidium, cesium, and francium, as atomic radius generally increases down a group in the periodic table.
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?
Potassium has a low ionization energy due to its large atomic size and one electron in its outermost shell, making it easier to remove that electron.
Which element had only one valance electron?
Hydrogen (H) Lithium (Li) Sodium (Na) Potassium (K) Rubidium (Rb) Cesium (Cs) Francium (Fr)
Which element does the first 7s electron appear?
The first 7s electron appears in francium (element 87) on the periodic table.
What element has its outermost electron is 7s1?
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.
Which element in the periodic table has the smallest ionization enegry?
francium
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.
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
Which element has the smallest first ionization energy Na K Rb Li?
The element with the smallest first ionization energy is Francium, as it is located in Group 1 of the periodic table and has the largest atomic size. Among the elements listed, lithium (Li) would have the smallest first ionization energy as it is closer to the upper right of the periodic table compared to sodium (Na), potassium (K), and rubidium (Rb).
