AP EAMCET · Chemistry · Classification of Elements and Periodicity in Properties
Identify the pair of elements with the highest and lowest electronegativity respectively
- A \(\mathrm{K}\) and \(\mathrm{Rb}\)
- B I and F
- C \(\mathrm{F}\) and \(\mathrm{Fr}\)
- D Fr and \(\mathrm{Li}\)
Answer & Solution
Correct Answer
(C) \(\mathrm{F}\) and \(\mathrm{Fr}\)
Step-by-step Solution
Detailed explanation
Fluorine (F) is the element with highest electronegativity, lying at the extreme right in the second period. Francium (Fr) is the most electropositive or least electronegative element, lying at the bottom left of the periodic table.
