Chapter 6, Problem 76A

Interpretation Introduction

Interpretation: The compound with greatest electronegativity from cesium and bromine needs to be determined.

Concept introduction: Electronegativity of an atom is defined as its ability to pull the shared pair of electrons towards itself, when present in a combined state in a compound.

Answer to Problem 76A

Bromine is more electronegative than cesium.

Explanation of Solution

In a periodic table, electronegativity decreases across the group and increases left to right in a period. Electronegativity of bromine is 2.96 and cesium is 0.79. Bromine is located above and right to the cesium element. Hence, electronegativity of bromine is higher than cesium.

Conclusion

Smaller atoms attract electrons more strongly than larger one. Hence, small atoms are electronegative than bigger one.
