Cesium is a group one metal which has a large atomic radius. This means that the outer shell of electrons is a great distance away from the pull of the nucleus which causes a decrease in the affect of the nuclear charge. There are many electron shells in between which causes shielding. This would reduce the atom's ability to pull electrons in a bond making it less electronegative. Group one elements would rather lose their outer shell electron to become stable than gain another electron.
What else can I help you with?
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.
Which element within a compound is shown first within the compound's name?
In a compound name, the element that appears first is usually the one that is the least electronegative or has the lower oxidation state. This element is named first, followed by the second element with an -ide suffix. For example, in "sodium chloride," sodium is listed first because it is less electronegative than chlorine.
What is the electronegativity difference between fluorine and francium?
The electronegativity difference between fluorine and francium is approximately 3.9. Fluorine is the most electronegative element on the periodic table, while francium is one of the least electronegative. This significant difference in electronegativity contributes to the reactivity and chemical behavior of these elements.
What is the least reactive element in the group 2 of the periodic table of elements?
The Zinc Family also known as group IIB is the second least reactive I believe. The least reactive family is the one with a full p sublevel, the noble gases, the next least reactive would be the family with a full d sublevel. Since group IIB has a full d sublevel, it must be the next least reactive family.
Which element shows least active chemical behavior Cs Rb Na?
Cesium (Cs) shows the least active chemical behavior among these elements. It is located at the bottom of Group 1 in the periodic table and has the largest atomic radius, making it the most reactive metal in Group 1. Rb (Rubidium) and Na (Sodium) are more reactive than Cs.
What element is the least electronegative on the periodic table?
Cesium, Cs
Which element is given first the more electronegative or less electronegative?
fluorine is most electronegative and cesium is least electronegative
Which two elements on the periodic table have the biggest electronegativity difference between two atoms?
The two elements with the largest electronegativity difference between their atoms are fluorine (F) and cesium (Cs). Fluorine is the most electronegative element on the periodic table, while cesium is one of the least electronegative elements.
What element is least electronegitive?
Francium is the least electronegative element
Which element has the lowest electronegativity value?
Electronegativity increases as you go from the bottom left corner of the periodic table to the upper right corner. The element with the lowest electronegativity is thus francium (Fr). However, this element is radioactive, and so generally the least electronegative element that you can really use is cesium (Cs). Generally speaking, this whole first column (the alkali metals) all have very low electronegativities, but the lower down the column, the lower the electronegativity.(Francium may not be the least electronegative element due to the relativistic effects, which is evident from its ionization energy (> Cs) and standard electrode potential (
What is the least electronegative element in the third period?
It is sodium metal.
What is the least electronegative element?
The least electronegative element is francium, which has a Pauling electronegativity value of 0.7. Francium is a highly reactive metal and is rare in nature.
Is oxide an element or an compound?
An oxide is a compound that contains oxygen and at least one other element that is less electronegative than oxygen.
What is Pauling scale?
The Pauling scale is a numerical scale used to measure the electronegativity of elements, developed by chemist Linus Pauling in 1932. It assigns a dimensionless value to each element, indicating its ability to attract electrons in a chemical bond. The scale ranges from around 0.7 for cesium, the least electronegative element, to 4.0 for fluorine, the most electronegative. This scale helps predict the nature of bonds between atoms, such as ionic or covalent character.
What is the least reactive element in group6?
Group seven is known as the halogen group. The least reactive element in group seven is astatine. Fluorine is the most reactive.
What is oxygen's favorite element?
I don't understand what "favorite" is supposed to mean in this context. Oxygen is highly electronegative and will preferentially combine with the least electronegative element available, but that's not really a matter of "favorite", it's a matter of energetics.
Which elements on the periodic have the lowest electrongativity?
The elements with the lowest electronegativity are found in Group 1 of the periodic table, specifically cesium (Cs) and francium (Fr). These alkali metals have very low electronegativity values due to their single valence electron, which they readily lose in chemical reactions. As a result, they have a weak ability to attract electrons from other atoms. Overall, cesium is typically recognized as the least electronegative element, with a Pauling scale value of about 0.79.
