Question

Given below are two statements:
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

• A. Both Statement I and Statement II are correct
• B. Both Statement I and Statement II are incorrect
• C. Statement I is correct but Statement II is incorrect
• D. Statement I is incorrect but Statement II is correct

Answer 1

The Correct Option is C

In order to solve this problem, we need to analyze both statements individually and assess their accuracy based on fundamental concepts in physics:

Statement I: Atoms are electrically neutral as they contain an equal number of positive and negative charges.
This statement is correct. An atom comprises protons, which are positively charged, and electrons, which are negatively charged. In a neutral atom, the number of protons equals the number of electrons, resulting in no net charge.

Statement II: Atoms of each element are stable and emit their characteristic spectrum.
This statement is incorrect. While atoms do emit a characteristic spectrum, they are not inherently stable. Stability varies among atoms; some are stable while others may be radioactive. The emission of characteristic spectra is often due to electrons moving between energy levels, not because atoms themselves are stable.

After evaluating both statements, we conclude: Statement I is correct but Statement II is incorrect.
