what is the element with the lowest electronegativity value cesium calcium fluorine silicon?
Answers
Answer:
The electronegativity value for calcium is 1. So the highest atomic number is of cesium with 8 shells between nucleus and valence electrons and tends to give its electrons readily, so it has the lowest electronegativity.

Answer:
Cesium(Cs) has the least electronegatvity
Explanation:
Electronegativity is how strongly an atom in a molecule will pull on shared electrons. All of the halogens have relatively high electronegativity because they all need one electron to fill their valence shells. Fluorine is the most electronegative element because the one empty space in its valence shell is in the second energy level, which is relatively close to the positively charged nucleus. Fluorine is the most electronegative element on the periodic table. Its electronegativity value is 3.98. Cesium is the least electronegative element. Its electronegativity value is 0.79. Electropositivity is the exact opposite of electronegativity, therefore, we can say that Cesium is the most electropositive element. Those elements requiring only a few electrons to complete their valence shells, and having the least quantity of inner electron shells between the positive nucleus and the valence electrons, are the most electronegative. The most electronegative of all elements are fluorine. Its electronegativity is 4.0. Metals have electronegativities less than 2.0. The least electronegative elements are cesium (Cs) and francium (Fr), with electronegativity values of 0.7. Therefore, Fluorine is the most electronegative element and cesium is the least electronegative element. As, half life of Francium is very less, as it is a radioactive element, therefore we usually consider Cs as the most electropositive or least electronegative element.
