AP EAMCET · Chemistry · Classification of Elements and Periodicity in Properties
Two statements are given below.
Statement I: Nitrogen has more ionization enthalpy and electronegativity than beryllium
Statement II: \(\mathrm{CrO}_3, \mathrm{~B}_2 \mathrm{O}_3\) are acidic oxides
Correct answer is
- A Both statements I and II are correct
- B Both statements I and II are not correct
- C Statement I is correct, but statement II is not correct
- D Statement I is not correct, but statement II is correct
Answer & Solution
Correct Answer
(A) Both statements I and II are correct
Step-by-step Solution
Detailed explanation
Ionization enthalpy depends on the (i) Size of the atom (ii) Effective nuclear charge (iii) Electronic configuration. In periodic table left to right ionisation enthalpy increases and nitrogen have half-field electronic configuration so its ionisation enthalpy is more.…
