C. The electrone

Question

Which of the following statements are not correct?

A. The electron gain enthalpy of F is more negative than that of Cl.
B. Ionization enthalpy decreases in a group of periodic table.
C. The electronegativity of an atom depends upon the atoms bonded to it.
D. AlO and NO are examples of amphoteric oxides.

Strategy:
 Review fundamental periodic trends. Electron Gain Enthalpy () has a  period anomaly, and Electronegativity is an intrinsic characteristic. Categorize oxides based on their pH properties.

Step 1: Evaluate each statement
- A: Chlorine has a more negative  than Fluorine because Fluorine's compact  orbital leads to high electron-electron repulsion. (Incorrect)
- B: Down a group, atomic size increases and valence electrons are further from the nucleus, so  decreases. (Correct)
- C: Paulin
