NEET (UG) 2024 — Question 19
Given below are two statements : one is labelled as Statement I and the other is labelled as Statement II :
Statement I: Atoms are electrically neutral as they contain equal number of positive and negative charges.
Statement II: Atoms of each element are stable and emit their characteristic spectrum.
In the light of the above statements, choose the most appropriate answer from the options given below.
- Option A:
Both Statement I and Statement II are correct
- Option B:
Both Statement I and Statement II are incorrect
- Option C:Correct
Statement I is correct but Statement II is incorrect
- Option D:
Statement I is incorrect but Statement II is correct
Answer: C
Step-by-step solution
Statement I is correct: atoms are electrically neutral because they contain equal numbers of protons (positive) and electrons (negative). Statement II is incorrect: although many atoms are stable and can emit characteristic spectra when excited, not all atoms are stable (e.g., radioactive atoms decay) and the emission of a characteristic spectrum is not a property of stability but of electronic transitions. Therefore, Statement I is correct and Statement II is incorrect. The correct option is C.
