NEETChemistryClassification of Elements and Periodicity in Properties

Four elements A , B , C , and D belong to the same short period of the periodic table. The sudden large jump in their successive ionization enthalpies occurs as follows: Element A : between _ i H₁ and _ i H₂ Element B : between _ i H₂ and _ i H₃ Element C : between _ i H₃ and _ i H₄ Element D : between _ i H₅ and _ i H₆ Which of these elements is expected to form the most acidic oxide?

Options

  1. AElement D
  2. BElement A
  3. CElement B
  4. DElement C

Correct answer

A. Element D

Step-by-step solution

The position of the massive jump in successive ionization enthalpies indicates the number of valence electrons an element possesses. For element A , the jump is after the first electron, meaning it has 1 valence electron (Group 1). For element B , the jump is after the second electron, meaning it has 2 valence electrons (Group 2). For element C , the jump is after the third electron, meaning it has 3 valence electrons (Group 13). For element D , the jump is after the fifth electron, meaning it has 5 valence electro
