TS EAMCET · Chemistry · Classification of Elements and Periodicity in Properties
Among the following, the pair of elements having same electronegativity values are I. \(\mathrm{H}\) and \(\mathrm{P}\) II. Be and \(\mathrm{Al}\) III. \(\mathrm{N}\) and \(\mathrm{Cl}\) IV. C and P
- A I, II and III
- B II, III and IV
- C I, III and IV
- D I, II, III and IV
Answer & Solution
Correct Answer
(A) I, II and III
Step-by-step Solution
Detailed explanation
Electronegativity is the tendency of an atom to attract a shared pair of electrons. Electronegativity of \(\mathrm{H} \approx \mathrm{P}, \mathrm{Be} \approx \mathrm{Al}\) and \(\mathrm{N} \approx \mathrm{Cl}\).
