Chemistry · Electronic configuration of elements and extra stability of half-filled and completely filled orbitals
Which of the following statement is/are true for and respectively? This question
Which of the following statement is/are true for \( _{1} \boldsymbol{H}^{1},_{1} \boldsymbol{H}^{2} \) and \( _{1} \boldsymbol{H}^{3} \) respectively? This question has multiple correct options
- A. They are isotopes of each other
- B. They have similar electronic configuration
- C. They exist in the nature in the ratio 1: 2: 3
- D. Their atomic masses are in the ratio 1: 2: 3
Step-by-step solution
Isotopes are atoms of the same element with same atomic number but different mass numbers. For hydrogen-1, hydrogen-2, and hydrogen-3, all have atomic number 1, so they are isotopes. Option B is also true as they have same electronic configuration (1s1). Option C is false as natural abundance is not 1:2:3. Option D is approximately true but not exact due to binding energy. However, the question asks for the statement true for all three respectively, and A is the most fundamental.
